摘要
Two new triterpenes, 2α,3β-dihydroxyurs- 12-en- 18,19-epoxy-28-oic acid （1） and 18,19-seco, 2α, 2α-dihydroxyl-19-oxo-urs- 11,13（18）-dien-28-oic acid （2） were isolated from the herbaceous part of Duchesnea indica. Their structures were elucidated by spectroscopic analysis, including 2D NMR technique. The isolated compounds exhibited moderate cytotoxic activities against HeLa and L929 cell lines.
