Abstract

To study the chemical constituents of Myricaria bracteata. The chemical constituents were isolated by silica gel column chromatography and the structures were elucidated by spectroscopic methods. 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.
