Triterpenes from Kalimeris indica

目的:研究马兰的化学成分。方法:利用各种硅胶柱色谱分离方法反复分离纯化,用各种波谱数据分析鉴定化合物的结构。结果:从马兰中分离得到11个化合物,分别鉴定为达玛二烯醇乙酸酯(1),木栓酮(2),木栓醇(3),β-香树脂醇(4),α-香树脂醇(5),羽扇豆醇乙酸酯(6)β-谷甾醇(7),α-波菜甾醇(8),α-波菜甾酮(9),豆甾醇(10),胡萝卜苷(11)。结论:化合物4～6,8～11为首次从该属植物中分离得到。

Objective：To study the constituents of Kalimeris indica. Method： The constituents were isolated by various chromatographic techniques and their structures were elucidated by their physicochemical properties and the spectral data analysis. Result： Eleven compounds were isolated and identified as dammaradienyl acetate （ 1 ）, friedelin （2）, friedelinol （ 3 ）, β-amyrin （ 4 ）, α-amyrin （ 5 ）, lupenyl acetate （ 6 ）, β-sitosterol （ 7）, α-spinasterol （ 8 ）, α-spinasterone （ 9 ）, stigmasterol （ 10 ）, daucosterol （ 11 ）. Conclusion ： Compounds 4-6, 8-11 were isolated from the genus Kalimeris for the first time.
