Abstract

Five new glycosides, quercetin 3'-O-beta-D: -galactopyranoside (1), quercetin 3-O-(2''-acetyl)-beta-D: -glucopyranoside (2), 4,6-dihydroxy-2-methoxyphenyl 1-O-beta-D: -glucopyranoside (3), 4-hydroxy-2,6-dimethoxyphenyl 1-O-alpha-L: -rhamnopyranosyl (1 --> 6)-beta-D: -glucopyranoside (4) and 3-methyl-but-2-en-1-yl beta-D: -glucopyranosyl (1 --> 6)-beta-D: -glucopyranoside (5), were isolated from Hypericum erectum Thunb. Their structures were established on the basis of spectral and chemical data.
