[Studies on the chemical constituents of the stems of Alyxia sinensis (I)].
OBJECTIVE
To demonstrate the chemical constituents of Alyxia sinensis.


METHODS
Phytochmical experiment was carried out, using column chromatograph technologies.


RESULTS
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), beta-sitosterol acetate(11), lupeol(12), betulin(13), stigmasterol(14), beta-sitosterol(15), ursolic acid(16), oleanolic acid(17).


CONCLUSIONS
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.
