摘 要: 从甘肃产维西香茶菜(Rabdosia weisiensis C.Y.Wu)的干茎叶中分离出5个贝壳杉烷型二萜化合物,用波谱学方法进行了结构鉴定,依次为:Kamebacetal A(工),Kamebanin(Ⅱ),Weisiensin B(Ⅲ),Macrocalyxin D(Ⅳ),Excisanin K(Ⅴ).用SRB法分别进行了体外细胞毒活性测试,结果表明化合物Ⅰ~Ⅴ对癌细胞株Bel-740,HO-8910都具有较强的细胞毒活性. Five ent-kaurane type diterpenoids were obtained from the dried stems and leaves of the R. weisiensis C. Y. Wu distributes in ZhangXian county of GanSu province. By spectroscopic means, their structures were identified as Kamebaeetal A ( Ⅰ ), Kamebanin ( Ⅱ ), Weisiensin B ( Ⅲ ), Maerocalyxin D (Ⅳ) and Exeisanin K( Ⅴ ). The antitumor activity was determined in vitro by the SRB assay. The result indicates that five compounds have significant eytotoxieity against Bel-7402 and HO-8910.
