Gynostemma Cucurbitaceae (Cucurbitaceae) plant kg Gynostemma Gynostemma [Gynostemma pentaphyllum (Thunb.) Makino] drying grass, climbing herbaceous perennial, mainly distributed in China, Japan, Korea and other countries. Gynostemma is one of the plants of the Araliaceae ginsenoside resources, health tonic, anti-cancer and senility, enhance physical fitness and improve lipid metabolism and other functions, known as the \This article summarized Gynostemma chemical composition and pharmacological studies on the basis of its study of the chemical composition of the system and the anti-tumor activity. Repeated column chromatography on silica gel, macroporous resin, Sephadex LH-20, inverting the ODS semi-preparative HPLC and other chromatographic means isolated 38 compounds from Gynostemma 75% ethanol extract. And by physicochemical properties, spectral analyzes (IR, NMR, MS, etc.) and chemical methods their structures were identified, namely: (23S)-21R-O-n-butyl-3β, 20ξ, 21 - three hydroxy -21 , 23 - epoxy dammar -24 -
