Two new flavonol glycosides from Gymnema sylvestre and Euphorbia ebracteolata

Two new flavonol glycosides, namely kaempferol 3-O-β-d-glucopyranosyl-(1 → 4)-α-l-rhamnopyranosyl-(1 → 6)-β-d-galactopyranoside () and quercetin 3-O-6″-(3-hydroxyl-3-methylglutaryl)-β-d-glucopyranoside (), 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.
