ABSTRACT

<p><b>OBJECTIVE</b>To demonstrate the chemical constituents of Alyxia sinensis.</p><p><b>METHOD</b>Phytochmical experiment was carried out, using column chromatograph technologies.</p><p><b>RESULT</b>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).</p><p><b>CONCLUSION</b>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.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To demonstrate the chemical constituents of Alyxia sinensis.</p><p><b>METHOD</b>The constituents were isolated by column chromatography and identified by advanced physical and spectral analysis.</p><p><b>RESULT</b>Eight compounds have been isolated and elucidated as bauereny acetate(18), scopletin(19), liriodendrin(20), pinoresinol-di-O-beta-D-glucopyranoside(21), daucosterol(22), flaxetin(23), esculin(24), aseculin(25).</p><p><b>CONCLUSION</b>These compounds were found from the plant for the first time, and compound 20,21,23-25 were found from Alyxiae genis for the first time, and compound 18 is firstly been isolated from natural source.</p>
