摘要
目的:对紫菀Aster tataricus L.f.的化学成分进行研究。方法:采用硅胶柱色谱、LH-20柱色谱进行分离,通过理化和波谱分析方法鉴定化合物结构。结果:从紫菀石油醚萃取部位分离得到9个化合物,分别鉴定为紫菀酮(1)、木栓酮(2)、表木栓醇(3)、蒲公英萜醇(4)、β-谷甾醇(5)、豆甾醇(6)、对羟基肉桂酸十六烷酯(7)、ll-hydroxy-10,11-dihydro-euparin(8)和lachnophyllic acid(9)。结论:其中化合物9为新的天然产物,化合物7、8为首次从紫菀属中分得。
Objective： To investigate the chemical constituents form Aster tataricus L. f.. Methods： Column chromatographic techniques were used for isolation and purification of chemical constituents of the plant and the structures were elucidated by spectroscopic analysis. Results： Nine compounds were isolated and identified as： shionone （ 1 ）, friedelin （2）, epi-friedelanol （ 3 ）, taraxerol （ 4 ）, β-sitosterol （ 5 ）, stigmasterol （ 6 ）, p-hydroxycinnamic acid hexadecyl ester（ 7 ）, ll-hydroxy-10, 11 -dihydro-euparin （8） and laehnophyllic acid （ 9 ） . Conclusion： Compound 9 was obtained as a new natural product, compounds 7, 8 were isolated from this genus for the first time.
