New flavonol glycosides from the leaves of Caragana brachyantha.
Nat Prod Res. 2015; 29(7):615-20.NP

Abstract

Two new flavonol glycosides, brachysides C and D, together with three known flavonol glycosides, were isolated from the leaves of Caragana brachyantha. The structures of brachysides C and D were elucidated on the basis of detailed spectroscopic analysis as quercetin 5-O-[α-L-rhamnopyranosyl-(1 → 6)-β-D-glucopyranoside]-7-O-[α-L-rhamnopyranoside] and quercetin 5-O-[α-L-rhamnopyranosyl-(1 → 6)-β-D-glucopyranoside]-7-O-[α-L-rhamnopyranoside]-4'-O-[α-L-rhamnopyranoside], respectively. The presence of flavonol tetra- and triglycosides bearing a sugar moiety at position 5 was the first report from this genus Caragana.
