摘　　要：目的研究美味猕猴桃Actinidia deliciosa根的化学成分。方法以95%乙醇为提取溶剂,经多种色谱方法分离,根据理化性质,结合谱学手段对化合物进行结构鉴定。结果从美味猕猴桃根中分离得到3个化合物,分别鉴定为2β,3β,28-三羟基-12,20(30)-羽扇豆二烯(1)、2α,3β,19α,24-四羟基-12-烯-28-乌苏酸(2)、2α,3β,23,27-四羟基-12-烯-28-乌苏酸(3)。结论化合物1为1个新的羽扇豆烷型三萜,命名为猕猴桃素A。Objective To investigate the chemical constituents from the roots ofActinidia deliciosa. Methods With 95% ethanol as the extraction solvent, various chromatography techniques were used to separate and purify the constituents and the structures were identified based on spectroscopic data. Results Three compounds were isolated from the roots of A. deliciosa and identified as lupa-12, 20（30）-diene-2β,3β,28--triol （1）, 2α, 3β, 19α, 24-tetrahydroxy-12-en-28-ursolic acid （2）, and 2α, 3β, 23, 27-tetrahydroxy-12- en-28-ursolic acid （3）. Conclusion Compound 1 is a new triterpenoid named actinidin A.
