Objective:
To study the chemical constituents of Myricaria bracteata.
Method:
The chemical constituents were isolated by silica gel column chromatography and the structures were elucidated by spectroscopic methods.
Result:
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.
Conclusion:
All compounds were obtained from M. bracteata for the first time.
