[Studies on chemical constituents in herb of Myricaria bracteata].
OBJECTIVE
To study the chemical constituents of Myricaria bracteata.


METHODS
The chemical constituents were isolated by silica gel column chromatography and the structures were elucidated by spectroscopic methods.


RESULTS
Eleven compounds were obtained and identified as rhamnetin, 3,5,4'-trihydroxy-7,3'-dimethoxyflavone, 3,5,4'-trihydroxy-7-methoxyflavone, quercetin-3-O-alpha-L-rhamnopyranoside, kaempferol, quercetin, chrysoerio, gallic acid, gallic acid ethylester, beta-sitosterol, daucosterol.


CONCLUSIONS
All compounds were obtained from M. bracteata for the first time.
