A new cardenolide from the roots of Streptocaulon tomentosum
A new cardenolide, (17 alpha)-H-periplogenin-3-O-beta-D-glucopyranosyl-(1-4)-2-O-acetyl-3-O-methyl-beta-fucopyranoside (1), was isolated from the roots of Streptocaulon tomentosum.
Characterization of the anticancer properties of monoglycosidic cardenolides isolated from Nerium oleander and Streptocaulon tomentosum
(Journal of Ethnopharmacology 134, 2011)
Aim of the study: For identification of the active constituents we investigated the anticancer activity of cardenolides from Streptocaulon tomentosum Wight & Arn. (Asclepiadaceae) and from Nerium oleander L. (Apocynaceae) ...
