Three quercetin glycosides, designated f₁, f₃, and f₅, were obtained from the fruits of Rosa multiflora THUNB. The structures of f₁ and f₃, new flavonol glycosides, were determined to be quercetin 3-β-D-glucopyranosyl-(1→4)-α-L-ramnopyranoside (I) and quercetin 3-β-D-glucopyranosyl-(1→6)-β-D-glucopyranosyl-(1→4)-α-L-ramnopyranoside (II), respectively, by means of acidic hydrolysis, enzymatic hydrolysis, hydrolysis of methylates, nuclear magnetic resonance measurement of trimethylsilyl ether and methanolysis of fully methylated compounds. f₅ was identified with quercitrin (III).
