Chemical constituents and cytotoxic activities from the root and the stem of Reevesia formosana

In our previous studies, we have reported 13 new cardenolide glycosides with potent cytotoxicities, reevesiosides A-I and epi-reevesiosides F-I from the root of Reevesia formosana (Sterculiaceae). Continuing investigation of the root and the stem of this species led to the isolation of three new lignanoids, reevesic acid, reevesilignan, and reevesiacoumarin, two new sesquiterpenes, reevesiterpenol A and reevesiterpenol B, one new triterpene,...
