New Metabolites of Rhodiola rosea. II. Hibiscetin Glycosides

Two new flavonoids ( 1 and 2 ) were isolated from the extract of flowers of Rhodiola rosea L. [ Sedum roseum (L.) Scop., Crassulaceae]. Their structures were established as hibiscetin 3- O -(3″- O -malonyl)- β -D-glucopyranoside-8- O-β -D-glucuronopyranoside (rhodirosin G, 1 ) and hibiscetin 3- O-β...

Summary:Two new flavonoids ( 1 and 2 ) were isolated from the extract of flowers of Rhodiola rosea L. [ Sedum roseum (L.) Scop., Crassulaceae]. Their structures were established as hibiscetin 3- O -(3″- O -malonyl)- β -D-glucopyranoside-8- O-β -D-glucuronopyranoside (rhodirosin G, 1 ) and hibiscetin 3- O-β -D-glucopyranoside-8- O -(2″- O -malonyl)- β -D-glucuronopyranoside (rhodirosin H, 2 ) using UV, IR, and NMR spectroscopy and mass spectrometry. Their antiradical activity was investigated.
