2、鉴定其结构。并对提取到的化合物进行了稻瘟霉和体外细胞毒(针对MKN一45人胃癌肿瘤细胞和HCT—l16人肠癌肿瘤细胞)的活性检测。结果:分离鉴定了5个三萜皂苷化合物,分别为24一dehydroechinosideA(1),echinosideB(2),echinosideA(3),holothurinB(4)和holothurinA(5)。化合物1~5对稻瘟霉的最小活性浓度分别为<7.9、<15.71、<7.9、<15.7、<7.9“g/ml,对MKN一45人胃癌肿瘤细胞的IC。值分别为1.60、0.18
3、、1.86、1.59、2.37Fmol/L,对HCT一116人肠癌肿瘤细胞的IC5。值分别为1.46、3.31、1.98、1.60、0.24Fmol/L。结论:化合物l为首次以原生产物形式得到的单体天然产物,2~5为首次从糙海参中分离得到5个化合物均显示显著的体外细胞毒活性。[关键词]糙海参;三萜皂苷;抗肿瘤活性[中图分类号]R979.1[文献标识码]A[文章编号]0258879X(2005)06—0626—06Studyonbioactivetriterpeneglycosidesofseacucumb
