General info
- Arcangelisia is a genus of flowering plants belonging to the family Menispermaceae. Its native range is Hainan to Indo-China and New Guinea.
- The genus Argangelisia comprises 3 species: A. flava, A. gusanlung, and A. typanopoda. (46)

Botany
• Abutra is a woody, perennial, climbing plant with a very long stem growing from the ground level to the canopy of trees. Old stems are about 5 centimeters thick, with a gray bark and yellow wood. Leaves are leathery, smooth, broadly ovate, 16 centimeters wide and 16 centimeters long, the tip abruptly pointed, the base obtusely round or subtruncate, with 5 veins radiating from the base, with one or two lateral nerves arising from the midvein above the middle. Inflorescence is axillary, pendulous and spicately panicled, usually clustered along the stems. Flowers are fragrant, yellowish, crowded and stalkless. Exterior perianth segments are 3, and small; interior ones are 6, oblong, much longer, and spreading. Fruit is nearly spherical, about 2 centimeters in diameter, green or yellowish green.

Growth form: A liana with cup-like petiole scars and injured stem produce yellow sap. Foliage: Petiole is 4 – 20 cm long, swollen at both ends and bend like a knee at the base. Leaves are ovate to elliptic (10 – 25 cm long and 5.5 – 19 cm wide) with rounded or slightly cordate leaf base and acuminate leaf tip. Leaves are palmately veined at the base with 1–3 pairs of secondary veins usually arising from above halfway along the midrib. Veins are prominent on both surfaces and possess hollow domatia in the secondary veins axils on the lower surface. Leaves dry matte with inconspicuous veins pattern. Flowers: Inflorescence is a slender panicle (10 – 50 cm long) and occurs axillary or on stem. Male flower has 3 – 4 tiny outer sepals (less than 1 mm long), 3 + 3 larger inner sepals which are elliptic to ovate (1.5 – 2.5 mm long) and stamens about 0.5 – 1 mm long. Female flower has 6 sepals (2.5 – 4 mm long) which are narrowly oblong and become reflexed. The reduced male organs in the female flower are tiny and scale-like. Female flower also has 3 carpels and a broad stigma. Fruit: Fruits are borne in a branched cluster (5 – 45 cm long) at the axillary or on the stem. Within the branched cluster, fruits usually occur in group of 1 – 3, often forming a club-shape. Each fruit is yellow and appears slightly laterally compressed (2.2 – 3 cm long and 2.5 – 3.3 cm wide), smooth and drying wrinkled. Endocarp is woody and the surface is covered densely with fibers.

Studies
Antioxidant / Cytotoxic / Anti-Breast Cancer:
Study evaluated the antioxidant and cytotoxic activities of A. flava, C. blumeanum and F. tinctoria: A. flava showed antioxidant activity and pronounced cytotoxic activity against human cancer cell line MCF-7 (breast adenocarcinoma). Berberine, palmatine and jatrorrhizine were isolated from A. flava. (1)
Antimalarial / Cytotoxic:
Study evaluated 49 plants and 228 extracts from plants traditionally use to treat malaria in south Vietnam for in-vitro activity against Plasmodium falcifarum and antitoxicity against human cancer cell lines HeLa and the embryonic lung MRC5 cell line. At concentration of 10 µg/ml
, 82 extracts showed antiplasmodial activity. Six plants, including A. flava, showed antiplasmodial activity with IC50 ranging from 0.4 to 8.6 µg/ml with good selectivity. (2)
Phytochemical / New Furanoditerpenes:
Study yielded four new furanoditerpenes plus fibraurin, fibleucin, and 6-hydroxyfibraurin. (3)
Antibabesial Activity / Protoberberine Alkaloids:
Study isolated palmatine, berberine, jatrorrhizine, dihydroberberine and 20-hydroxyecdysone. Four compounds caused significant inhibition of Babesia gibsoni, an intraerythrocytic parasite that causes hemolytic anemia in wild and domesticated dogs. The mechanism was possibly through prevention of parasite invasion of erythrocytes and inhibition of growth. (4)
Genotoxicity:
In a study of 138 medicinal plant preparations used in the Philippines were studied for genotoxicity. 12, including A. flava exhibited detectable genotoxicity.
Furanoditerpenoids / Fibaruretin: Furanoditerpenoids are secondary metabolites found in Menispermaceae plants, found to possess anti-inflammatory and antimalarial activities. Study of the roots of A. flava isolated a furanoditerpenoids compound, fibaruretin. (6)
Protoberberine Alkaloids / Anti-Babesial:Stems yielded palmatine, berberine, jatrorrhizine, dihydroberberine and 20-hydroxyecdysone. Compounds 1-4 showed growth inhibiting effects on Babesia gibsoni in culture. (B. gibsoni is an emerging pathogen in dogs.) (7)
Berberine: A. flava yields the plant alkaloid berberine. Review lists its physiological effects: anti-diarrheal, anti-malarial, anti-tumor, stimulates cardiac contractility and anti-arrhythmic, anti-inflammatory and antihepatotoxic.
Anti-Babesial: Study evaluated the inhibitory effects of 45 selected plant extracts from Central Kalimantan, Indonesia in invitro and its acute toxicity to mice. Arcangelisia flava showed to have appreciable antibabesial activity without toxicity to mice. (9)
Hepatoprotective: In vivo studies of secondary metabolites of abutra (akar kuning) saponin extracts without alkaloids showed hepatoprotective activity in paracetamol induced liver damage in Sprague Dawley rats. (10)
Anti-Malarial / Anti-Telomerase: Berberine, extracted from Arcangelisia flava dose-dependently inhibited telomerase activity in erythrocytic cycle of Plasmodium flaciparum suggested P. falcifarum telomerase may be a potential target for future malarial chemotherapy. (12)
Antihypertensive / Anti-Cancer: A study of twenty-two medicinal plants showed the pepsin hydrosylates of Arcangelisia flava bark to have antihypertensive (ACE inhibitory) and anticancer (≥50 % inhibition of human cancer cell lines) activities. (13)
• Natural Food Additive / Antimicrobial / Acidity-Stabilizing Effects in Palm Sugar: Study investigated the antimicrobial and acidity-stabilizing effects of yellow root extract. A water extract showed antimicrobial activity against Salmonella typhi, Staphylococcus aureus, and Trichophyton rubrum. The extract showed ability to stabilize the acidity of fresh palm sap due to fermentation mechanism. Toxicity testing using Brine shrimp lethality assay showed A. flava to be a natural product without toxicity. Results suggest A. flava can be used as a safe natural food additive, especially in the production of palm sugar. (15)
• Safety Study on Hepatotoxicity: Study sought to determine if A. flava is hepatotoxic to rats. A freeze-dried preparation was administered intraperitoneally to rats. Only an isolated case of SGPT elevation was noted; the majority were within normal range. (1
7)
• Pharmacologic Effects / Berberine: Study was done to determine whether the pharmacologic effects of A. flava extracts are attributable to the berberine content, the principal alkaloid content of the plant. The study did not settle the issue, but concluded the following: (1) IV doses of the extract to a dog caused hypotension, bradycardia, and increased myocardial contraction. (2) In isolated turtle heart, the extract caused a decreased in heart rate. (3) IV to dogs, the extract caused an initial stimulation of respiratory rate followed by depression without changes in tidal air. (4) Increase in ileal amplitude and tone. (5) Intraarterially, produced paralysis of the gastrocnemius-soleus contractions of the dog. (18)
• EGFR Inhibition / Potential Benefit in HER2-Positive Breast Cancer / Berberine: Cancer cell over-proliferation can be caused by abnormalities of EGFRs, a group of receptors that play a role in initiation of cell proliferation. EGFRs inhibition could inhibit cancer cell proliferation process. Study evaluated the potent secondary metabolites of akar kuning as EGFRs inhibitors. Over-expression activity of EGFR-2 often occurs in breast cancer. Study predicted that berberine has EGFR inhibitory activity, especially EGFR-2 and has potential for HER2-positive breast cancer therapy. (19)
• Selective Cytotoxicity Against Breast and Colon Cancer Cell Lines / Leaves: Study of an ethanolic extract of A. flava leaves is cytotoxic and selective against breast and colon cancer.

• Potential for α-Glucosidase Inhibition / Antidiabetic / Bark: Study evaluated the bark extract of yellow root plant for α-glucosidase enzyme. Results showed very weak inhibitory activity towards α-glucosidase enzyme. The supposed antidiabetic mechanism of yellow root-stem is via inhibition of α-glucosidase enzyme and stimulation of pancreatic ß-cells, thereby increasing insulin production or secretion. (22)
• Neuraminidase Inhibition / Fibleucin: Study evaluated the relationship between secondary metabolites of akar kuning and neuraminidase (NA) with molecular docking study and to determine the most potent NA inhibitor from metabolites from akar kuning. Study isolated a total of 11 secondary metabolites, including fibleucin. In silico molecular molecular docking and pharmacophore optimization indicated fibleucin could be considered as NA inhibitor, with a potential as anti-influenza particularly to H5N1 with oseltamivir resistance, (see constituents above) (23)
• Antibacterial Against Aeromonas hydrophila: Study evaluated the antibacterial activity of A. flava against Aeromonas hydrophila. The chloroform solvent exhibited the widest preventive zone (17.25 mm) on A. hydrophila. (24)
• Antibacterial / Molecular Docking Study / Berberine: Molecular docking study was done on several secondary metabolites of akar kuning against active site of several antibacterial receptors known for many antibiotics including cell wall protein, nucleic acid, synthesis inhibitors and antimetabolites. Findings showed that among 11 metabolites studied, 6-hydroxyfibraurin, berberine, and fibleucin showed lowest free energy of binding between 11 antibacterial receptors compared with natural substrates or inhibitors from each receptor. Results showed the for the selected secondary metabolites of akar kuning, the main mechanism of action was inhibition of protein synthesis which was shown by berberine. (25)
• Antidiabetic / Antioxidant / Leaves: Study evaluated the in-vitro antioxidant and antidiabetic activity of hexane, ethyl acetate, and methanol extract of Kaya kuning leaves. The methanol extract showed highest scavenging activity on superoxide and hydroxyl radical, while the ethyl acetate extract showed highest scavenging activity on DPPH radical. Compared to standard acarbose, the hexane and EA extracts showed potent potent antidiabtic activity, with the EA extract showing highest potency. Antidiabetic activity was evaluated using α-amylase and α-glucosidase assays. (26)
• Hypocholesterolemic / Stem / Root: A previous study showed a methanol extract of A. flava leaves reduced TC and LDL cholesterol, and reduced the atherogenic index value and number of foam cells. The antihyperlipidemic effect was attributed to berberine and flavonoid in the extract. In this study in hyperlipidemic rats, the stem extract reduced TG, TC, and LDL cholesterol levels. The hypo-cholesterolemic effect could also be attributed to berberine and flavonoid. (27) Study evaluated the anti-hypercholesterolemic extract of A. flava root extract in male mice induced by high fat diet of quail egg yolks. The A. flava extract at 9.5 mg, 10 mg, 38 mg / 20gBB decreased total cholesterol by 10%, 13%, and 17%, respectively. The effect was still different from simvastatin 10 mg. (40)
• Berberine and Jatrorrhizine / Src Inhibitor in Cancer Therapy: Proto-oncogene tyrosine protein kinase (Src) protein is one of the targets in various cancer therapies such as leukemia. Study evaluated the potential secondary metabolites of akar kuning as Src inhibitors Molecular docking was done using quercetin and dasatinib as reference ligands. Docking results showed berberine to have the highest affinity. Results showed the combination of berberine and and jatrorrhizine is predicted to be optimally used as an Src inhibitor to cancer therapy. (28)

(36)
Suppression of Cancer Cell Lines / Non-Apoptotic Pathway / Leaves: Study evaluated an ethanolic leaf extract for mechanism of cytotoxicity. The EEAFL obtained from 16.1 g/100g of dried leaves yielded 16.1%. The EEAFL tends to trigger necrosis rather than apoptosis on HeLa, MCF-7 and WiDr. The higher the concentration, the more cells to undergo necrosis, except on HeLa cell line. (37)
Antimalarial / Inhibition of Heme Polymerization: An earlier investigation showed A. flava can inhibit P. falcifarum growth. Study evaluated the antimalarial activity and IC50 based on inhibition of heme polymerization. Results showed the water extract had an IC50 pf 601 ppm, and FTIR and GA-MS study identified the chemical constituent, stigmastan. (39)
Anti-Inflammatory / Phytoconstituents against Nitric Oxide Synthase / Molecular Docking: Study sought to discover inducible nitric oxide synthase (iNOS) inhibitors from Morus sp. and A. flava for anti-inflammatory drug candidates. Molecular docking of phytoconstituents yielded 10 phytoconstituents in A. flava and eight compounds in Morus sp. interacting with Glu377, an important amino acid residue in the iNOS binding pocket. The phytoconstituents fit the pharmacophore features generated from AT2 or SEITU complex with iNOS with potential as iNOS inhibitors. (41)
Effect on Estrous Cycle / Bark: Study evaluated the effects of A. flava bark decoction on the estrous cycle of female albino mice with bark decoction administered orally for one month. Results showed a decrease in the number of estrous cycles in the treated groups. The proestrus stages of the group that received 3 mL of decoction showed prolonged mean duration. (42)
EGFR Inhibitors / Breast Cancer Therapy: Akar kuning (A. flava) is known for anticancer activities. Several secondary metabolites have shown antiproliferative activity towards cancer cells. Study aimed to determine the most potent secondary metabolites of akar kuning as several EGFRs inhibitors. Molecular docking results showed berberine provided the most negative free energy of binding and lowest inhibition constant towards all EGFRs. Berberine showed activity as EGFR inhibitor, especially EGFR-2, with potential for development as HER2-positive breast cancer therapy. (44)
Anti-Osteoarthritis / Inhibition of Nitric Oxide / Stems: Study evaluated a 70% ethanol extract of A. flava stems on inhibition of NO production in RAW 264.7 cells induced with lipopolysaccharide (LPS) and IL-1ß in osteoarthritic rats induced with monosodium iodoacetate (MIA). The extract at 10, 30, and 90 mg/200gBW increased latency time, reduced joint swelling, reduced IL-1ß levels in the serum in osteoarthritis rat model. Results suggest potential of the 70% ethanol extract as anti-osteoarthritis drug. (47)

Biologically active constituents in the dichloromethane extract of A. flava, palmatine (1) and fibraurin (2) exhibited antifungal properties, with MICs ranging from 15.62 to 62.5 µg/mL against Candida species. Compound 1 showed minimum fungicidal concentration (MFC) of 62.5 µg/mL against Candida glabrata and C. krusei. Compound 2 showed MFC f 125 µg/mL against both Candida species. Results suggest the compounds can provide references for the next stage in antifungal drug design. (48)
Interleukin 1ß Inhibitor / Stems: Study evaluated the phytochemical compounds in 70% ethanol extract of A. flava stems. Extract revealed alkaloids, flavonoids, furano-diterpene, hydroxyquinoline, phenylpropanoid, phenol, and fatty acids. Molecular docking study of 15 compounds analyzed by
LC-MS/MS
showed compounds 3-hydroxy-3',4',5'-trimethoxyflavone (∆G=-7.72 kcal/mol), fisisaine (∆G=-6,91 kcal/mol), and demethyleneberberine (∆G=-6.85 kcal/mol) demonstrated high affinity for binding to target protein. Results suggest the phytochemical compounds from A. flava may serve as adjunctive therapy or source of structures in drug discovery for treatments targeting interleukin-1ß. (50)
Anticancer / HepG2 Hepatocellular Cancer Cells / Roots: Study evaluated the anticancer activity and apoptosis induction of ethanolic extract of A. flava roots on HepG2 cancer cell lines. Results showed IC50 of 109.14 µg/ml against HepG2 cells. Apoptosis assay showed significant decrease in intact cells (80.10%) and a significant increase in early apoptosis (7.9%) and late apoptosis of HepG2 cancer cells (4.9%) compared to control. Proliferation of HepG2 cells declined significantly (75.9% in 48 and 72 hours after treatment with IC50s of 77.5 and 64.3%, respectively. Results suggest potential for hepatocarcinoma treatment.

                                                            List of Understudied Philippine Medicinal Plants
                                          New plant names needed
The compilation now numbers over 1,500 medicinal plants. While I believe there are hundreds more that can be added to the collection, they are becoming more difficult to find. If you have a plant to suggest for inclusion, native or introduced, please email the info: scientific name (most helpful), local plant name (if known), any known folkloric medicinal use, and, if possible, a photo. Your help will be greatly appreciated.
