Glycosides from Breynia fruticosa and Breynia rostrata.
Glycosides, 3-acetyl-(-)-epicatechin 7-O-beta-glucopyranoside (1), 3-acetyl-(-)-epicatechin 7-O-(6-isobutanoyloxyl)-beta-glucopyranoside (2), 3-acetyl-(-)-epicatechin 7-O-[6-(2-methyl-butanoyloxyl)]-beta-glucopyranoside (3), (5Z)-6-[5-(2-hydroxypropan-2-yl)-2-methyl-tetrahydrofuran-2-yl]-3-methylhexa-1,5-dien-3-O-beta-glucopyranoside (4), hydroquinone O-[6-(3-hydroxyisobutanoyl)]-beta-galactopyranoside (5), 4-(4-O-beta-glucopyranosyl-phenoxy)-1-O-beta-glucopyranosyl-1,3-benzenediol (6), 7,8-erythro-dihydroxy-3,4,5-trimethoxy-phenyl-propane8-O-beta-glucopyranoside (7), 6,7-dimethylbenzofuranol 5-O-beta-xylopyranosyl-(1-->6)-beta-glucopyranoside (8), along with 30 known glycosides, were isolated from Breynia fruticosa and Breynia rostrata (Euphorbiaceae). Their structures were determined on the basis of spectroscopic analysis and chemical methods.
