Puerarin (Kakonein), an isoflavones found in the root of Radix puerariae, is a 5-HT2C receptor and benzodiazepine site antagonist. Pueraria is employed clinically to treat cardiovascular diseases in China. Another study showed that puerarin also possessed anti-cancer properties. Puerarin at 25 μM dose-dependently reduces HT-29 cellular growth with an increase of bax and decreases of c-myc and bcl-2.
体内研究:In hypercholesterolmic diet plus administration of puerarin (300 mg/kg/day, p.o.) rats, Puerarin markedly attenuated the increased total cholesterol induced by hypercholesterolmic diet in both serum and liver. LD50: Mice 738mg/kg (i.v.)
