摘要：
Two new flavonol glycosides, namely kaempferol 3-O-beta-D-glucopyranosyl-(l --> 4)-alpha-L-rhamnopyranosyl-(1 --> 6)-beta-D-galactopyranoside (1) and quercetin 3-O-6"-(3-hydroxyl-3-methylglutaryl)-beta-D-glucopyranoside (2), have been isolated from the aerial parts of Gymnema sylvestre and Euphorbia ebracteolata, respectively. Their structures were determined on the basis of chemical and spectroscopic methods. (C) 2004 Elsevier Ltd. All rights reserved.
