尾叶香茶菜化学成分研究

Studies on the Chemical Constituents of Rabdosia excisa

目的:研究唇形科植物尾叶香茶菜Rabdosia excisa地上部位的化学成分。方法:采用硅胶柱色谱、Sephadex LH-20凝胶柱色谱、反相硅胶柱色谱等柱层析方法进行分离纯化,依据化学方法和现代波谱技术进行结构鉴定。结果:从尾叶香茶菜地上部位分离得到9个单体化合物,分别鉴定为dayecrystal A(1),acetylsventenic acid(2),sventenic acid(3),trichokaurin(4),maoyerabdosin(5),pedalitin(6),syringic acid(7),β-谷甾醇(8)和胡萝卜苷(9)。结论:化合物1、2、3、4和5为首次从尾叶香茶菜植物中分离得到。

Objective： To study the chemical constituents of the aerial parts of Rabdosia excisa. Methods： The compounds were isolated and purified by silica gel column chromatography and their structures were established on the basis of modern spectroscopic analysis. Results： 9 compounds isolated from the aerial parts of this plant were identified as： dayecrystal A （1）, acetylsventenic acid （2）, sventenic acid （3）, trichokaurin （4）, maoyerabdosin （5）, pedalitin （6）, syringic acid （7）, β-sitosterol （8） and daucosterol （9） . Conclusion ： It is the frist time that compound 1, 2, 3, 4 and 5 were isolated from Rabdosia excisa.
