【Abstract】 Objective:To demonstrate the chemical constitutes of Alyxia sinensis .Method:Phytochmical experiment was carried out, using column chromatograph technologies.Result:Five compounds have been isolated from the petroleum ether soluble part of the stems of A. sinensis . Their structures have been elucidated respectively as heptatriacontane(1), octatriacontane(2), 20 noatriacontannone(3), 20 nonatriacontanone(4), 20 tetraacontanoe(5), physcion(6), emodin(7), chrysophanol(8), coumarin(9), stigmasterol acetate(10),β sitosterol acetate(11),lupeol(12), betulin(13), stigmasterol(14), β sitosterol(15), ursolic acid(16), oleanolic acid(17).Conclusion:All these compounds are firstly been isolated from A. sinensis . And compound 5～9,10,11 are also been separated from Alyxiae genus for the first time.更多还原
