目的:研究尾叶香茶菜 Rabdosia excisa 花和果实的化学成分。方法:利用硅胶柱色谱法进行分离和纯化化合物。通过理化性质和波谱数据鉴定结构。结果:从尾叶香茶菜的花和果实部分共分离鉴定了 16 个化合物: 豆甾醇 (Ⅰ); α-香树脂醇棕榈酸酯 (Ⅱ);熊果酸 (Ⅲ); 2α, 3α, 19-三羟基-12-烯-28-乌索酸(Ⅳ); 2α-羟基乌苏酸(Ⅴ); 2α-羟基齐墩果酸(Ⅵ); isodonal(Ⅶ);maoyecrystalE (Ⅷ); kamebakaurin (Ⅸ); macrocalyxinG (Ⅹ); epinodosinol (Ⅺ); rabdosichuanin C (Ⅻ); kamebacetal A (ⅩⅢ); 冬凌草甲素(ⅩⅣ); enmenol-glucoside (ⅩⅤ); lasiodonin (ⅩⅥ). 结论:除了化合物Ⅰ, Ⅱ, Ⅸ , Ⅻ, ⅨⅣ, 其他化合物都是首次从尾叶香茶菜中发现。

AIM： To study the chemical constituents in the flowers and fruits of Rabdosia excisa. METHODS： The compounds were isolated and purified by silica gel column chromatography and their structures were identified by spectroscopic methods. RESULTS： Sixteen compounds isolated from the flowers and fruits of this plant were identified as： stigm asterol （ I ）, a-amyrin palmitate （II）, ursolic acid 0II）, 2a, 3a, 19-trihydroxy-urs-12-en-28-oic acid （IV）, 2a-hydroxyursolic acid （V）, maslinic acid （VI）, isodonal （VII）, maoyecrystal E （VIII）, kamebakaurin （IX）, macrocalyxin G （X）, epinodosinol （XI）, rabdosichuanin C （XII）, kamebacetal A （XIII）, oridonin （XIV）, enmenol-glucoside （X V）, and lasiononin （XVI）. CONCLUSION： All the constituents were found in Rabdosia excisa for the first time, except constituents [II, IX, XII and X IV.
