| Abstract: | In this research,8 compounds were isolated from the ethyl acetate( Et OAc) barks of Quercus acutissima Carruth with the silica gel column chromatography,Sephadex LH-20,HPLC et al. On the basis of the spectra analysis,the 8 compounds were elucidated as the flowing:( +)-5'-methoxy-isolariciresinol-9'-O-α-L-rhamnopyranoside( 1),isolariciresinol rhamnopyranoside( 2),( +)-lyoniresinol-3α-O-α-L-rhamnopyranoside( 3),quercetin( 4),5,7,3',4'-tetrahydroxy-flavonol-3-O-glycoside( 5),β-amyrin( 6),β-sitosterol( 7),and daucosterol( 8). Among these compounds,compounds 1-6 and 8 were obtained from this plant for the first time. |
