[Studies on chemical constituents from Tibetan medicine wangla(rhizome of Coeloglossum viride var. bracteatum)].
OBJECTIVE
To study the chemical constituents of Tibetan Madicine Wangla.


METHODS
Sepearing the chemical constituents by means of chromatography and identifying their structures on the basis of MS and NMR spectra and TLC with authentic samples.


RESULTS
Eight 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).


CONCLUSIONS
All the compounds were obtained from genus Coeloglassum for the first time. The compound I is a new natural product.
