Abstract:
OBJECTIVETo demonstrate the chemical constituents of Alyxia sinensis.
METHODPhytochmical experiment was carried out, using column chromatograph technologies.
RESULTFive 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).
CONCLUSIONAll 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.
