Abstract
In addition to three known flavonol glycosides, kaempferol 7-O-α- l-rhamnopyranoside , rhodionin and rhodiosin, a new kaempferol glycoside was isolated from the roots of Rhodiola crenulata. The structure was identified as kaempferol 7-glucosyl(1 → 3)rhamnoside by means of spectral analysis.
