The structure of four new flavonol glycosides isolated from the epigeal part of Rhodiola rosea have been established: 7-O-α-L-rhamnopyranosylgossypetin (rhodiolgin), 8-O-β-D-glucopyranosyl-7-O-α-L-rhamnopyranosylgossypetin (rhodiolgidin), 8-O-β-D-glucopyranosyl-7-O-α-L-rhamnopyranosylherbacetin (rhodionidin), and 3-O-β-D-glucopyranosyl-8-O-β-D-xylopyranosylherbacetin (rhodalidin).The properties of the previously undescribed incomplete methyl ethers of herbacetin and gossypetin obtained during the structural analysis of the glycosides have been studied.It has been found that diazomenthane methylates the 5-OH groups in the diglycosides investigated.
