Abstract

From the aerial parts of Verbascum songaricum the two new triterpenoid saponins songarosaponin E, F and the known buddlejasaponin I have been isolated and identified as 3-O-([beta-D-glucopyranosyl-(1-->4)-beta-D- glucopyranosyl-(1-->3)]-[beta-D-glucopyranosyl-(1-->2)]-beta-D- fucopyranosyl)-olea-11,13-diene-3 beta, 23,28-triol, 3-O-([beta-D- glucopyranosyl-(1-->4)-beta-D-glucopyranosyl-(1-->3)]-[beta-D- glucopyranosyl- (1-->2)]-beta-D-fucopyranosyl)-olea-11,13-diene-3 beta, 16 beta, 23,28-tetrol and 3-O-([alpha-L-rhamnopyranosyl-(1-->4)-beta-D-glucopyranosyl-(1-->3)]- [beta-D-glucopyranosyl-(1-->2)]-beta-D-fucopyranosyl)-13 beta, 28-epoxyolea- 11-ene-3 beta, 16 beta, 23-triol.
