显脉香茶菜化学成分的研究

Studies on the Chemical Constituents of Rabdosia nervosa

从江西宜丰地区产的显脉香茶菜Raadosia nevrosa(Hemsl)C. Y. Wu et H. W. Li茎叶中分得10个单体,经光谱解析和理化鉴别,确定了5个化合物的结构,其中2个为β-seco-entkaurene型二萜,nodosin(1)、epinodosinol(2),其余为β-谷甾醇、乌苏酸及胡萝卜甙。

Five compounds were isolated from the stems and leaves of Rabdosia nervosa. On the basis of spectral analysis and chemical identifi- cation, their structures were identified as no-doisn (I), epinodosinol (2),β -sitosterol,urso- lic acid and daucosterol respectively. Compounds (2) and daucosterol were first obtained from R. nervosa.
