The cytotoxic activity of extracts of Asclepias albicans (Asclepiadaceae) was traced to uzarigenin (2), desglucouzarin (3) and a new cardenolide glycoside, uzarigenin 3-O-β-D-glucopyranosyl (1→4)-β-D-glucopyranoside (4). The latter compound also displayed significant antitumor activity against P-388 lymphocytic leukemia.
