中越猕猴桃根二萜化学成分的研究

Studies on the Triterpenoids Constituents of Indochina Actinidia Root

从中越猕猴桃Ａｃｔｉｎｉｄｉａ ｉｎｄｏｃｈｉｎｅｎｓｉｓ的根部中分离得到 ５个化合物，根据其理化性质和波谱分析，分别鉴定为２α，３α，２４－三羟基－１２－烯－２８－乌苏酸（Ｉ），２β，３β，２３－三羟基－１２－烯－２８－乌苏酸（Ⅱ），２４－ｈｙｄｒｏｘｙｔｏｒｍｅｎｔｒｉｃ ａｃｉｄ（Ⅲ），熊果酸（Ⅳ）和β－谷甾醇（Ⅴ），以上化合物均首次从该植物中获得，其中化合物Ⅲ为从该属植物中首次分离得到。

Five compounds were isolated from the root of Actinidia indochinensis Merr. and identified as 2α, 3α, 24-trihydroxy-urs--12--en-28--oi acid (Ⅰ), 2β, 3β, 23-trihydroxy--urs-12--en--28-oi acid (Ⅱ ), 24-hydroxytormentric acid (Ⅲ ), ursolic acid (Ⅳ ) and β-sitosterol by spectral data and physicochemical properties. Commpound Ⅲ was isolated from Actinidia L. for the first time.
