title: Phenolic glycosides from Pyrola japonica.
abstract: Five new phenolic glycosides, 2-beta-D-glucopyranosyloxy-5-hydroxyphenylacetic acid methyl ester (4), 4-hydroxy-2-[3-hydroxy-3-methylbutyl]-5-methylphenyl beta-D-glucopyranoside (5), 4-hydroxy-2-[(E)-4-hydroxy-3-methyl-2-butenyl]-5-methylphenyl beta-D-glucopyranoside (7), 4-hydroxy-2-[(2E,6Z)-8-beta-D-glucopyranosyloxy-3,7-dimethylocta-2,6-dien-1-yl]-5-methylphenyl beta-D-glucopyranoside (8), and 2,7-dimethyl-1,4-dihydronaphthalene-5,8-diol 5-O-beta-D-xylopyranosyl(1-->6)-beta-D-glucopyranoside (10), were isolated from the whole plants of Pyrola japonica (Pyrolaceae), together with androsin, (-)-syringaresinol glucoside, homoarbutin, pirolatin, hyperin, monotropein and chimaphilin.
