Gen info
- Abrus is a genus of flowering plants in the pea family, Fabaceae, and the only genus in the tribe Abreae. It contains 13-18 species, but is best known for a single species jequirity (Abrus precatorius).
- in Rajasthan, India, the Chirmi song is associated with the plant
. Among the traditional Zulu people the beads is a source of craft economy. (78)
- During the Tang Dynasty, a poem by Wang Wei titled "One-Hearted" (Xang Si), is said to likely refer to Abrus precatorius as a "red bean" (hona dou).   (77)
- The seeds of Abrus precatorius or Gunjja are very consistent in weight, even under different moisture conditions due to the water-impermeable seed-coat. The Indians once used the seeds to weigh gold using a measure called a Ratti (gunjja), where 8 Ratti equals1 Masha , and 12 Masha equals 1 Tola (11.6 grams). (84)

Saga is a slender, twining, branched, annual vine that reaches a length of 9 meters or less. It is sparingly hairy or nearly smooth. Leaves are alternate, from 5 to 10 centimeters long and compounded into pinnate arrangement of about 20 to 40 leaflets to each leaf; each leaflet oblong, rather thin, from 1 to 3 centimeters long and with an abrupt terminal point. Inflorescence is an axillary raceme, shorter than the leaves with numerous crowded flowers. Flowers are pink to purple or salmon in color, attaining 1 centimeter in length. Calyx teeth short and standard petal ovate, the wings narrow, and the keel arched. Stamens are 9, the filaments of which united into a tube with a slit above. Ovary with many ovules with a short style. Fruits are pods, oblong and turgid, 2.5 to 5 centimeters long and about 1.5 centimeters wide. Seeds are 3 to 5 in a pod, round and shiny, half-red and half-black. Color of seeds is the the most recognizable characteristic of this species.

Toxicity !
• Seeds, roots, and leaves are all poisonous. Toxin is released when the hard outer cover of the seed is pierced, the toxin released then absorbed in the intestine. Toxin is released by chewing or drilling holes in the seeds for beadwork, ornaments or jewelry. (51)
• The plant is a common cause of accidental or intentional poisoning in the tropics. The estimated lethal dose for humans is 0.1-1.0 µg/kg. (
* The seeds have yielded abrin A and C, both sharing the same toxic mechanisms.
• Abrin is an intensely poisonous albumin. A dose of 1/1000 mg to 1/2000 mg per kilogram body weight injected subcutaneously is considered poisonous.• Seeds are exceedingly toxic (not to be taken internally).
• Fatal poisoning has been reported in children chewing as little as half a seed.
• Intact seeds remain impervious to gastric fluid and pose less of a toxicologic potential. (51)
• The toxic principle chemically and pharmacologically resembles ricin.
• Toxicity case report after ingestion of 3-4 seeds of AP causing acute demyelinating encephalitis, coma and death. (See below)

• Onset of toxicity may occur in 1 to 3 days; symptoms may persist for longer than 10 days. (51)
Kansasaga beans are extremely toxic, containing various types of toxic albumins. Symptoms of poisoning include diarrhea, vomiting, debility, stoppage of urine, hallucinations, etc. Observe extreme care in administering.
An infusion of bruised seeds, when applied to the conjunctiva, may cause fatal poisoning from abrin absorption through the conjunctiva. It is a power irritant which can cause ecchymoses and edema at the site of inoculation. In high concentrations, it will cause severe conjunctivitis, permanent corneal opacities, and even destruction of the eye.
Interestingly, it is reported that when injected into animals in infinitesimal doses, the animal rapidly acquires immunity to the poison.
• Necklaces made of pierced seeds can cause contact dermatitis. (51)

Clinical Profile of A. precatorius Poisoning: Study reports on the incidence and clinical presentation of A. poisoning of 30 patients presenting with an alleged history of consumption of seeds to the RMMCH Emergency Room in India. Male to female ratio was 1:4—females indulge in greater number in deliberate self-harm. Mild hypokalemia, attributed to excess fluid loss, was seen in 40% of patients. Major symptoms were vomiting (100%) and diarrhea (67%) which may be bloody. There may be severe dehydration, low blood pressure, hallucinations, seizures, and hematuria. Severe cases may be associated with liver, splenic and renal failure. 7% of patients of patients may die following ingestion of the seeds. (41)
Cerebral Venous Thrombosis Due to Abrin Toxicity: Study reports on a case of intentional A. precatorius poisoning in a young girl that caused cerebral venous thrombosis. While the mechanism for CVT is matter of speculation, the author suggests the possible cause of widespread vascular endothelial damage and a procoagulant state like dehydration. Treatment was supportive. Early first aid is gastric lavage and absorbents (activated charcoal). (43)
A Case of Hemorrhagic Gastroduodenitis: Study reports on a case of acute hemorrhagic gastro-duodenitis following ingestion of bright red and black beans later identified as A. precatorius. With vigilant monitoring, the patient survived without residual illness. (47)
• Abrin Toxicity: LD50 of abrin given intraperitoneally to mice is 0.04 mcg. 5 mg of the alkaloid is reported to toxic to humans. In goats, ground seeds at 1 to 2 g/kg/day can cause death in 2 to 5 days. (51)
• Retrospective Study on 112 Patients with A. precatorius Poisoning: Retrospective study reports on 112 cases of Abrus poisoning describing clinical features and outcome. Majority were females (78&), ages were between 13 and 30 years (81%), with diarrhea as most common symptom (66%) with blood present in the stools (33%). Six patients died with a mortality rate of 5.35%. (56)
• Survey: In a survey of 30 people, 83% were familiar with the peony seed; 40% uses it, and 67% ignores that the seed is toxic. (72)
- Seed Detoxification: (1) The Tamil Siddhas have suggested various methods called "suththi seythal" for for purification of the seeds , which is done by boiling the seeds in milk and then drying them. (2) Seeds are soaked in water for ten hours and boiled.  (3) In Ayurveda,. seeds are purified by boiling them in milk or steamed with the help of buttermilk.  (4)  Swedana is a traditional Ayurvei process of seed detoxication: seeds are boiled in water for 3 hours, followed by extraction of the seeds by cold maceration. (84 (75)

Renal Protective:
Study of seed extract of AP on alcohol-induced renal damage in rats concludes that the seed extract is protective on the kidney against alcohol-induced parenchymal damage. (1)
• Antiplatelet / Anti-Inflammatory / Antiallergic / Isoflavanquinones / Roots: Study of roots isolated five iso-flavanquinones. Abruquinones D, E, and F exhibited remarkable inhibitory effects on platelet aggregation. Abruquinones A, B, D, and F showed strong anti-inflammatory and anti-allergic effects. Abruquinones A, B, D, and F showed an IC 50 of less than 03 µg/ml for inhibition of superoxide formation and IC50 of less than 1 µg/ml for inhibition of release of both ß-glucoronidase and histamine from mast cells. (2)

Hypoglycemic / Hypolipidemic:
Study on the aqueous seed extract of AP showed strong hypoglycemic and hypolipidemic effects with a reduction of atherogenic risk predictor indices. The action of A precatorius was dose-dependent. (3)
Antifertility / Sperm Antimotility:
(1) Extract study showed that AP possesses a reversible sperm antimotility activity. (2) Methanol extract study of A precatorius seeds showed inhibitory effect on the motility of washed human spermatozoa. The effect of motility was essentially reversible. (3) Study of aqueous seed extract in male albino mice showed a male reproduction system with a dose-dependent reduction in testicular sperm count and motility.
Antifertility / Ovulatory Blockage :
Study of methanolic extract of Abrus precatorius seeds showed highly significant alterations in the pattern of estrous cycle, a significantly prolonged diestrous phase, a significant decrease in the proestrous phase and a total blockage of ovulation in one group. (7)

On hemagglutination titer (HT) test, the extract showed a suppressive effect at all doses. There was also a dose dependent increase in Phagocytic Index (PI). (44)
Abrin A: Study purified Abrin A from the seeds of A. precatorius. Biological properties were similar to Abrus protein, abrin C, i.e., toxic to cell-free protein synthesis and binds D-galactose. Results show abrin A is a mixture of isolectins; and both abrin A and C are closely related with the same mechanism of toxic action. (12)
Toxicity Study: Study of toxic effects of aqueous extract of A precatorius in white rats showed decreased in RBC, WBC, increased ALT and AST, testicular degeneration and sperm cell reduction. The results caution its use for medicinal purposes.(9)
Toxicity / Demyelinating Encephalitis: Study reports a case of acute demyelinating encephalitis in 30-year old female attributed to ingestion of 3 to 4 seeds of 'ratti.' The patient developed bloody diarrhea and deep coma, and died in three days due to progressive central nervous system depression. (5)
Hepatocelluar Carcinoma / Cytotoxic and Protective Effects: Study of the protective effects of an aqueous/ethanolic extract in NDEA-induced hepatocarcinogenesis in rats showed strong cytotoxic effects on HepG2 cells with dose-dependent reduction in various hepatic markers. (14)

Anti-Serotonergic : Study of an EA extract of AP leaves on frog fundus strip using sumatriptan as standard showed antiserotonergic activity with a graded dose response in contraction. (15)
Wound Healing / Antimicrobial: Study of crude seed and methanol extracts of white form of AP showed early wound healing activity in with and without infection. The wound healing was attributed to gums, mucilages, tannins or phenolic compounds in the seeds. (16)
Mast Stabilizing / Anti-Allergic / Anti-Asthmatic: The ethanol extract of AP significantly protected against egg albumin induced degranulation of mast cell and inhibited area of leakage of dye in passive cutaneous anaphylaxis. Results concluded AP possesses anti-asthmatic potential. (2
Antioxidant / Antiproliferative: Study evaluated various leaf extracts for antioxidant and antiproliferative properties. The extracts showed strong antiradical properties, Fe++ chelating ability, and good inhibitory ability for lipid peroxidation. Tested on four different human tumor cells lines (human colon adenocarcinoma, human retinoblastoma cancer cells, human hepatocellular carcinoma cells and leukemia cells) the extract showed capabilities of inhibiting survival of tested cancer cell lines. Results showed high antioxidant and antiproliferative activity with potential applications in the treatment of diseases caused by ROS. (19)
Anti-Oogenic / Fertility Regulator / Seed Extract: Study evaluated the seed extract for its effect of ova formation in Swiss albino mice. Results showed follicles in different stages of atresia and deviated oetrous cycle revealing a potential as antifertility agent and embodies Abrus to be a prolonged oral fertility regulator. (20)
Antidiabetic / Seeds: Study evaluated the antidiabetic effect of chloroform-methanol extract of A. precatorius seed in alloxan diabetic rabbits. Results showed antidiabetic properties similar to chlorpropamide, with similar percentage reduction in blood glucose level. (22)
Antioxidant / Leaves: Study evaluated a methanol extract of leaves for antioxidant activity by various assays.

Anticataractic / Antioxidant: Study evaluated in vitro anticataract and antioxidant activities of ethanolic seed extract of A. precatorius against calcium-induced cataractogenesis using goat lenses. Results showed the extract protected the lens against calcium-induced oxidative damage which might help in delaying the progression of the cataract. (26)
Antihistaminic Activity in Clonidine Induced Catalepsy: Study evaluated an ethanolic extract of leaves for antihistaminic activity using clonidine induced catalepsy in mice. Clonidine induces catalepsy by releasing histamine from mast cells which is responsible for different asthmatic conditions. Results showed the extract of PA leaves and chlorpheniramine maleate inhibited clonidine induced catalepsy.   (27)
Effect on Androgenic Alopecia / Seeds: Study evaluated petroleum ether and ethanolic extracts of seeds for reversal of androgen (testosterone by I.M.) induced alopecia in male albino wistar rats. Rats treated with the extracts did not develop alopecia. Inhibition of 5α-reductase activity by extracts and finasteride suggest the reversal of androgen induced alopecia by inhibiting the conversion of testosterone to dihydrotestosterone. Study concludes the anti-androgenic alopecia activity was due to inhibition of 5α-reductase activity. (28)
Neuroprotective / Hypoxic Neurotoxicity: Study evaluated the neuroprotective effects of a petroleum ether extract of aerial parts in hypoxic neurotoxicity induced rats. The extract showed neuroprotedtive effects. It significantly promoted spatial behavior and restored the decreased levels of enzymes (glutamate, dopamine, and acetylcholinesterases) which were reduced by the hypoxia. (29)
Gastroprotective / Leaves: Study of ethanolic extract of leaves on ethanol-induced and aspirin+pylorus ligation-induced peptic ulcer in rats showed anti-ulcer activity attributed to its antioxidant, antisecretory, and cytoprotective mechanisms. (
Abrine as Chemical Marker / Shodhana: Abrin is one of the most toxic compounds known to man, and collectively refers to five glycoproteins viz. abrus agglutinin and the toxic principles, abrins A-D, Seeds also contains the indole alkaloid, abrine. To be used in Ayurvedic formulations, seeds are treated by a process called "Shodhana", which denatures the toxin abrin. The presence of abrine in the seeds after "Sodhada" is used as a potential chemical marker in formulations or as indicator in cases of poisoning with AP  seeds. (
Hair Growth Promoter / Antifungal / Seed Oil: Study evaluated the hair growth promoting effect of A. precatorius seed oil and its effect on head fungal infection in female wistar albino rats. Results showed the seed oil to be a potent hair growth promoter comparable to minoxidil treated animals. It also showed antifungal effect comparable to Itraconazole. (
Anti-Lice / Seed Oil: Study evaluated a petroleum ether fraction of AP seeds against head louse i.e. Pediculus humanus capitis. Results showed excellent anti-lice activity comparable with standard benzyl benzoate. (
Antimalarial / Leaves: Study evaluated the antimalarial activity of aqueous extract of leaf in Swiss albino mice. Results showed potential antiplasmodial activity against Plasmodium berghei comparable to halofantrine at dose level of 25 mg/kg. (
Detoxification of Seeds: Death has been reported in children from ingestion of one or two seeds. The human fatal dose of abrin—the toxalbumin is 0.1 - 1.0 microgram/kg. Detoxification to remove toxicity of the seeds may be achieved by boiling the pounded seeds in kanji or cow's milk for 3 hours. Heat denatured abrin looses its haemagglutinating toxicity. Research has showed retention of immunomodulatory activity of heat-denatured or tryptic-digested abrin, while loosing toxicity. Correspondence also mentions an Ayurvedic antidote: juice of Amaranthus (Tandulja) and sugar. (
Antifertility / Suppression of Spermatogenesis / Seeds: Study evaluated ethanol seed extracts of Arbus precatorius seeds on male mice (Balb-C) fertility. Results suggest suppression of spermatogenesis with histomorphological evidence of decrease in epididymis tubule size and epithelial height, and reduction in sperm number in the tubular lumen. In higher doses, there was significant decrease in plasma testosterone. (
Paradox of Human Equivalent Dose Formula / LD and Toxicity: Human Equivalent Dose (HED) which is equal to animal dose multiplied by animal km (metabolism constant) divided by human km was used to project LD50 of 15 monogastric animals. The LD50 of aqueous leaf extract of AP in mice was estimated between 2559.5 and 3123.3 mg/kbw. Therapeutic safe dose range for the animals was 1-12.5 mg/kbw for 7 days. At a dose ≤200 mg/kbw the leaf extract showed a hematinic effect. At higher dose ≥200 mg/kbw it showed hemolytic effect in rat. At dose of ≥25.0 mg/kg the extract might be organotoxic in hamster, guinea pig, rabbit, monkey, cat, dog, baboon, child and adult human if administered orally for a period of 7 days. (
Contraceptive / Spermatogenesis Effect / Seed Oil: Study evaluated the contraceptive effect of seed oil in Wistar rats. Treatment showed a significant decrease in caudal sperm count and testosterone level. The antifertility effect was completely reversible on withdrawal of the drug. (
• Immunomodulatory / Seeds: Study evaluated the immunomodulatory activity of aqueous extract of Abrus precatorius seeds in Swiss albino mice. Results showed an inhibitory effect on immune functions in mice as evidenced by reduction in antibody titre, delayed hypersensitivity response and increase in phagocytic index. (
Anthelmintic / Seeds: Study of ethanolic extract of red seeds showed anthelmintic activity against earth worms Pheretima posthuma. Albendazole was used as standard drug. (
In Vitro Cytotoxicity / MCF-7 Cell Lines / Seeds: Study evaluated the in vitro cytotoxic effects of ethanolic and ethyl acetate extracts against MCF-7 cells lines. Tamoxifen was used as standard. Results showed that seeds of AP has cytotoxic properties and a potential source of antitumor agents. (see study above) (
Anticancer / Murin Mastocytoma Cancer Cell Line (P815) / Leaves: Study evaluated the in vitro anticancer activity of aqueous extract of Abrus precatorius leaves against murin mastocytoma cancer cell line (P815). Results showed a dose dependent cytotoxic effect. (see constituents above) (48)
Effect of A. precatorius and Amaranthus spinosus Combination on Male Fertility: Study evaluated the effect of A. precatorius and A. spinosus as male contraceptives independently and in combination. Study suggests A. precatorius showed sperm toxic effects. A. spinosus prevents cell death, and could improve sperm performance, even at a low dose. While A. spinosus showed no negative effect on male rat fertility, it normalized the infertility due to A. precatorius and the alteration of biochemical parameters induced by AP treatment, indicating a role in minimizing toxicity. The apparent reinforcement of action may be a possible means of avoiding undesirable side effects of A. precatorius which induces males infertility. (49)
• Toxicity Study / Leaves: Study evaluated the toxicity of aqueous extract of leaves in 20 male white rats over a period of 18 days at doses of 400, 800, and 1600 mg/kg of extracts. Results showed decrease levels of packed cell volume, Hb, RBC count, WBC count, together with increased levels of serum protein, ALT, AST, AP, and total bilirubin. Histologically, there was testicular degeneration as well as reduction in sperm cells with scattered Sertoli cells. Findings showed the aqueous extract of leaves was toxic and suggests caution in its use for medicinal purposes. (9)
• Potential Source of Antioxidants / Leaves: Study of leaves showed A. precatorius is a potential source of antioxidants with a potential for use in food and biological systems. A methanol extract exhibited varying degree of antioxidant activity in a dose dependent manner. The antioxidants can be used as food additives to delay oxidative deterioration of foods and as nutraceutical in food formulations against degenerative diseases. (see constituents above) (52)
• Antihyperglycemic / Insulin Secretagogue Activities / Leaves: Study evaluated a methanolic extract of leaves for in vivo antihyperglycemic activity and in vitro insulinotropic effect in streptozotocin induced diabetic rats. The methanol extract exhibited antihyperglycemic activity which might involve an insulin secretagogue effect by pancreatic beta cells physiological pathways via K+-ATP channel dependent and independently, along with an effect on Ca2+ channels. (54)
• Fertility Effects / Seeds and Leaves: Study evaluated the effect of methanolic extract of seeds and leaves of Abrus precatorius on implantation, hormonal profile, reproductive index and sexual behavior in adult female Wistar rats. Results showed A. precatorius seeds have an antifertility effect on female rats while leaf extracts were very effective as a fertility enhancing agent. (57)
• Antioxidant / Anti-Inflammatory / Analgesic / Seeds: Study evaluated the antioxidant, anti-inflammatory, and analgesic activity of A. precatorius ethanolic seed extracts. Results showed potent antioxidant activity by DPPH radical scavenging assay, significant anti-inflammatory activity with 62.68% at 375 mg/kg by carrageenan induced method, and significant analgesic activity by tail flick and tail immersion method. (58)
• Antidiabetic / α-Glucosidase Inhibitory Activity / Leaves: Study evaluated the potential of 80% methanolic extract of Abrus precatorius leaves for α-glucosidase inhibitory activity and glucose diffusion effect. Results showed a significant inhibitory effect on glucose diffusion. The inhibitory effect on glucose absorption was attributed to the plant's ability to inhibit intestinal α-glucosidase enzyme. (59)
• Acute and Subacute Toxicity Study / Seed: Study evaluated the acute toxicity of aqueous extract of Abrus precatorius seed in mice and Wistar rats by oral and intraperitoneal routs while subacute toxicity was evaluated in Wistar rats by IP route. LD50 was greater than 5000 mg/kg p.o. and 0.71 mg/kg i.p. in mice and 315.20 mg/kg p.o. and 0.35 mg/kg i.p. in rats. Results showed moderate toxicity and advises caution in its use in ethnomedicine. (
60) Study evaluated the toxic effects of seeds from A. precatorius in experimental rats. Pathological and anatomic findings revealed the extract of peony seeds had a poisonous effect on the endothelial wall in the rats. The findings could be correlated with observed clinical manifestations. (72)
• Male Antifertility / Seeds: Study evaluated the antifertility activity of abrus precatorius ethanolic seed extract administered intraperitoneally in  S
wiss male albino mice. Lower concentration (40 mg/kbw) of extract showed temporary antifertility activity while higher dose (80 mg/kbw) gave relatively more permanent antifertility effect. (61)
• Silver Nanoparticles / Antibacterial / Leaves: Study reports on the fast, easy, cost-effective, and eco-friendly green synthesis of silver nanoparticles using Abrus precatorius leaf extract with AgNO3 as reducing agent. The silver nanoparticles showed antibacterial activity against Escherichia coli and Bacillus thuringiensis. (62)
• Paradox of Human Equivalent Dose Formula / Toxicity / Leaves: The translated mouse-human LD50 is 197.9-241.5 mg/kbw, showing a high level of sensitivity of humans to Abrus precatorius leaf poisoning. The safe human therapeutic dose for a period of 3 days may be 1.0 mg/kbw, while the STDs for other animals are higher, for ex: hamster 9.1 mg/kg, rat 6.6 mg/kg, guinea pig 6.5 mg/kg, rabbit 3.0 mg/kg, monkey 2.9 mg/kg, cat 1.9 mg/kg and dog 1.8 mg/kg. (63)
• Antiplasmodial / Leaves: Study yielded a new pterocarpan from a dichlormethane extract of leaves. Crude extracts displayed brine shrimp lethality and in vitro antiplasmodial activity. A methanolic extract showed more toxicity against Plasmodium falcifarum than brine shrimp. (see constituents above) (64)
• Neuromuscular Blocking Effects: Study of ethanol extract of leaves, seeds, and roots of A. precatorius showed neuromuscular blocking effects. The extract showed a similarity to d-tubocurare vis-a-vis the pattern of neuromuscular blockade. (66)
• α-Amylase Inhibitory Triterpene / Lupenone / Leaves: In an Indonesian study of 18 plants screening for porcine pancreatic α-amylase inhibitors, extract of A. precatorius leaves showed potent inhibitory activity. Fractionation of the extract isolated a triterpene ketone, lupenone (1), a potent a-amylase inhibitor, together with 24-methylenecycloartenone (2) and luteolin (3). The mode of activity was mixed inhibition. (67)
Renoprotective / Seeds:
Study strongly indicated that the aqueous extract of seeds has a protective effect on alcohol-induced renal injury. Measurement of malondialdehyde level indicated the effect may be related to the attenuation of alcohol-mediated lipid peroxidation of renal parenchymal cells. (69)
• Antibacterial / Dried Seeds: Study evaluated the antibacterial properties of different extracts of dried seeds of Abrus precatorius by Agar well diffusion method against Gram-positive (Staphylococcus aureus, Bacillus subtilis) and Gram-negative (Escherichia coli, Klebsiella pneumonia) bacteria. Among the extracts, the isopropyl alcohol and ethyl acetate extracts of seeds showed significantly antibacterial activity compared with standard drug gentamycin. (71)
• Anthelmintic / Leaves: Study evaluated the anthelmintic potential of crude methanolic extract of leaves of Abrus precatorius on Indian earthworm Pheretima posthuma and Tubifex tubifex. Piperazine citrate was used as standard. Results showed the ME exhibited significant anthelmintic activity at all test doses as vermifuge and vermicidal with highest activity at higher concentration of 15 mg/ml. (74)
• Detoxification of Seeds / Anti-Inflammatory Potential of Detoxified Extract: Study reports on the Shodhana process, swedana (boiling) of Abrus precatorius seeds using water as medium. In hemagglutination assay, the non-detoxified extract showed higher agglutination of RBCs than detoxified extract suggesting removal of toxic hemagglutinating proteins by Shodhana. Cytotoxicity assay in HeLa showed higher reduction in growth percentage of cells with non-detoxified extract compared to detoxified extract indicating successful detoxification. In anti-inflammatory studies using carrageenan induced paw edema model in rats, the detoxified extract exhibited significant inhibition of rat paw edema comparable to Diclofenac sodium. Absence of toxicity and retention of anti-inflammatory activity of detoxified Abrus seed extract confirmed the Swedana process is effective for detoxification without affecting its therapeutic potential. (75)
• Fertility Disrupting Potential / Arresting Spermatogenesis and Suppressed Fertility / Seeds:
Study evaluated the contraceptive potentials of various extracts of A. precatorius seeds in male albino rats. Methanol and aqueous soluble seed extracts caused infertility at varying degrees. Testes histology showed marked atrophy of seminiferous tubules with disruption of germinal epithelium and atrophy of Leydig cells. Homone assays showed significant decrease in serum testosterone, FSH and LH that likely caused suppressed spermatogenesis of male rats, which led to reduction of pregnancy rate of untreated fertile female rats. Results showed potential for regulation of male fertility. (76)
Bronchodilator / Leaves: Study
evaluated a methanolic extract of leaves of A. precatorius for bronchodilator activity using various in vivo and in vitro models in guinea pigs.  The extract was effective against histamine and acetylcholine-induced contractions. The extract exhibited maximum relaxation relaxation effect at a  concentration of 100 mg/ml. Results showed dose dependent bronchodilator activity justifying its traditional use in the treatment of asthma. (80)
Saponins / Abrusosides / Oolong Tea Replacement / Leaves: Study
of methanol extract of ginseng oolong tea yielded a new sweet-tasting cycloartane-type saponin, 3β-O-[β-D-glucuronopyranosyl(1→2)]-β-D-6-acetylglucopyranosyl)-(20S,22S)-3β,22-dihydroxy-9,19-cyclolanost-24-en-26,29-oic  acid (9), along with five new compounds. The compounds showed different sugar chains connected to the abrusogenin molecule. Saponin profiles of four commercially available ginseng oolong samples and Abrus precatorius leaves were compared. Study showed the abrusosides could serve as replacement for the sweet taste. responsible for the sweet taste of the tea. (80)
Seasonal Effects on Phytoconstituents of Leaves: Study evaluated the seasonal effects on photosynthetic pigments, nutrients,  flavonoids, and  polyphenol and antioxidant activities of  Abrus precatorius. The highest foliar photosynthetic pigments and nutrients were observed  in monsoon (June-August) and lowerst in late monsoon *September to November). Maximum flavonoid content was detected in early monsoon while highest polyphenol content and antioxidant activity of the leaf extract was seen in late monsoon. (83)
