Mungo is an erect, annual herb branching at the base, more or less clothed with spreading, brownish hairs. Leaves are long-petioled, compound, with three leaflets which are ovate and entire, broad based with pointed tips, 8 to 15 centimeters long, the lateral ones being inequilateral. Flowers are yellow, about 1 centimeter long, arranged near the end of the short stalks. Pods are linear, hairy, spreading, 6 to 8 centimeters long, about 6 millimeters wide, and covered with scattered, long, brownish hairs. Seeds are 4 to 6 millimeters in length.

Hypotensive: The study showed all the extracts were hypotensive and contained bioactive proteinaceous substances and stimulated urine flow. Combinations of the extracts showed subtractive or additive effects. (1)
Anti-irritation: Clinical studies on the anti-irritation effects of mung bean (Phaseolus aureus) extract in cosmetics: The study of extracts applied to irritant-containing cosmetic formulations showed considerable anti-irritation efficacy and suggesting a potential use for cosmetic products. (2)
Cardiovascular Effects: Previous studies have shown the hypotensive effect of green beans, common rue and kelp. In this study, green beans and kelp showed negative chronotropic effects, while rue showed positive chronotropic and inotropic effects. A combination of all three showed subtractive effects on the decrease of atrial rate. The three plants interacted to modify their various cardiovascular effects. (3)
Hypolipidemic / Antiatherogenic: Changes in serum lipids in normal and diabetic guinea pigs on feeding Phaseolus aureus (Green gram): Study showed green gram feeding showed lowering of both free and esterified fractions of cholesterol, significant lowering of triglycerides and decreased the total cholesterol / phospholipid ration indicating its antiatherogenic nature. (4)
Hypolipidemic: Hypercholesterolemic rats supplemented with Isoflavones biochanin A and formononetin) from three pulses, including P mungo, and p-coumaric acid showed hypolipidemic activity.
Anti-Irritation Effects / Cosmetics / Vitexin / Isovitexin: Ethanolic extract isolated vitexin and isovitexin, previously suspected of antioxidant and anti-inflammatory activities. Study confirmed anti-irritation effects and suggests that the mung bean extract could be applied to cosmetic products.
Germination and Antioxidant Capacity: The study evaluated the effect of germination of raw mung beans and sprouts on antioxidant capacity and content of antioxidant compounds. Results showed germination of mung beans and soybean seeds is a good process for obtaining functional flours with greater antioxidant capacity and more antioxidant compounds than the raw legumes. (9)
Trypsin Inhibitor / Pancreatic Effects: Study evaluated the effect of green gram trypsin inhibitor (GGTI) and raw green gram meal (RGG) on experimental animals. Elevated levels pf protease and amylase were observed in the pancrease, with a significant variation in amylase activity, together with active proliferation of acinar cells. Histological study showed hyperplasia of the acinar cells. (10)
Anticonvulsant / Leaves: Study evaluated the anticonvulsant activity of chloroform and methanol extracts of leaves of Vigna radiata in albino Wistar rats on electrically and chemically induced seizures. In MES (maximal electroshock seizures), Vr leaves sowed most significant (p,0.01) anticonvulsant effect. (13)
Antimicrobial / Sprouts: Study of chloroform and methanol extracts of mung bean sprouts showed antimicrobial activity against all tested gram negative bacteria ( P. aeruginosa, E. coli, Salmonella spp.)with the exception of K. pneumonia. The methanol extract showed more significant activity against P. aeruginosa compared to the chloroform extract. (14)
Antibacterial / Sprouts: Study evaluated the antibacterial activities of extracts of Vr against pathogens causing food borne diseases. Methanol extracts showed significant concentration dependent antibacterial activity against almost all the test pathogens. (see constituents above) (15)
Antisepsis / Sprouts: HMGB1, a nucleosoma protein, has been established as a late mediator of lethal systemic inflammation. Study explored the HMGB-1 inhibiting capacity and therapeutic potential of mung bean coat (MBC) extract in vitro and in vivo. The MBC extract dose-dependently attenuated LPS-induced releases of HMGB-1 and several chemokines in macrophage culture. Results suggest MCH extract if protective against lethal sepsis possibly by stimulating autophagic HMGB1 degradation. (16)
Anticancer / Cytotoxicity / Immunomodulatory / Sprouts: Study evaluated the anticancer and immunomodulatory activity of mung bean sprouts (MBS) against human cervical and hepatocarcinoma cancer cells. Results showed significant cytotoxic effects exerted by MBS extract against the cancer cell lines. The cytotoxicity to HeLa and HepG2 was highly selective. The MBS extract was a potent inducer for apoptosis in treated human cancer cells via caspase-dependent and maybe caspase-independent pathways. The effects may involve strong, multi-mechanisms, and synergistic anticancer and/or immunomodulatory effects. (17)
Anti-Inflammatory / Mung Bean Testa: Study investigated the effects of ethanol extracts of mung bean testa (MBT) on metabolic inflammation-induced lipogenesis in gastrocnemius muscle of KK-Ay diabese mice. An in vitro pilot study with 3T3-L1 cells showed vitexin, the functional chemical in MBT, inhibited inflammation induced-lipogenesis with lower amounts of IL-6 and MCP-1. Functional compounds in MBT ethanol extracts such as vitexin and isovitexin may regulate intracellular lipogenesis and adipogenesis via anti-inflammatory mechanisms and MEK/ERK pathways in KK-Ay mouse model. (18)
Silver Nanoparticles / Callus Culture: Study showed callus cultures of Vigna radiata are suitable for the biosynthesis of bio-compatible nanoparticles as compared to microbes or plant parts. (19)
• Lectin / Antidiabetic Potential: Study evaluated lectins from Vigna radiata for antidiabetic activity. Seeds yielded a galactose specific lectin and evaluated for antidiabetic activity in an alloxan induced diabetic model in Wistar rats. Results showed significant (p<0.001) reduction in elevated sugar levels. Activity was attributed possibly to an insulinmimetic mechanism as evidenced by binding with insulin antibodies in Western Blotting Analysis. (22)
• Major Lectins / Alpha- and Beta-Glucosidase Activity / Seeds: Study of Vigna radiata seeds using exchange and gell filtration chromatography yielded two major D-galactose-specific lectins, MBL-I and MQBL-II. MBL-I was found to have alpha-glucosidase activity, while MBL-II was associated with beta-galactosidase activity. (23)
• Whitening Effect / Inhibition of Melanogenesis / Vitexin and Isovitexin / Seeds and Sprouts: Study evaluated the inhibitory effects on melanogenesis of EA and MC fraction of 80% methanol extracts of mung bean seeds and sprouts. Results showed inhibition of melanogenesis more effectively than argutin, a known whitening agent. Also, the in-vitro tyrosinase inhibitory activity on mushroom tyrosinase was higher in the EA fraction. Active components of the EA fraction were identified as flavones vitexin and isovitexin. (24)
• Antidiabetic: Study of an aqueous extract of V. radiata in STZ-induced diabetic mice showed significant antidiabetic activity at 200 mg/kg and 300 mg/kg, the latter showing higher activity. (25)
