摘　　要：香茶菜属植物富含结构多样、新奇的对映-贝壳杉烷二萜及其衍生物,前期对柔茎香茶菜Rabdosia flexicaulis的化学成分研究尚不够系统,仅从中发现3个这类化合物。为了寻找结构新颖、活性显著的二萜化合物,采集了四川省道孚县的柔茎香茶菜地上部分,采用多种柱色谱法和波谱分析手段,从乙酸乙酯部位中分离并鉴定出6个二萜化合物,新化合物命名为flexi-caulin E(1),其余已知化合物分别为forrestin B(2)、inflexarabdonin D(3)、7α-hydroxydehydroabietic acid(4)、15-hydroxydehydroabietic acid(5)、pomiferin F(6)。其中化合物1~3为对映-贝壳杉烷二萜,化合物2、3为首次从该种植物中分离得到。化合物4~6为首次从该属植物中分离得到的芳香松香烷型二萜。The genus Rabdosia is famous for the abundance of diverse and novel ent-kaurane diterpenoids.However,only a few ent-kauranoids have been discovered from R.flexicaulis since the investigation on its chemical constituents is not systematic.To find novel bioactive diterpenoids,the ethyl acetate extract of the above ground part of R.flexicaulis in Daofu County,Sichuan Province was obtained by column chromatography.One new compound and five known ones were identified as flexicaulin E(1),forrestin B(2),inf-lexarabdonin D(3),7α-hydroxydehydroabietic acid(4),15-hydroxydehydroabietic acid(5),and pomiferin F(6)by spectral techniques.Compounds 1-3 were the ent-kaurane diterpenoids isolated from this species for the first time.Compounds 4-6,aromatic abie-tanoids,were isolated from the genus Rabdosia for the first time.
