Abstract:
OBJECTIVETo study the chemical constituents of Tibetan Madicine Wangla.
METHODSepearing the chemical constituents by means of chromatography and identifying their structures on the basis of MS and NMR spectra and TLC with authentic samples.
RESULTEight compounds were isolated as 4-[(4-hydroxyphenyl) methoxy]benzenemethanol(I), 4,4'-dihydroxydiphenyl methane(II), 4,4'-dihydroxydibenzyl ether(III), gastrodin(IV), 4-hydroxy benzenemethanol(V), 4-hydroxybenz aldehyde(VI), beta-sitosterol(VII) and beta-daucosterol(VIII).
CONCLUSIONAll the compounds were obtained from genus Coeloglassum for the first time. The compound I is a new natural product.
