Five new glycosides from Hypericum erectum Thunb.

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.
