Two new aporphine alkaloids, isofiliformine ( 1) and cassythic acid ( 3), along with 22 known compounds were isolated from whole herb of Cassytha filiformis. Cassythic acid ( 3), cassythine ( 4), neolitsine ( 7), and dicentrine ( 8) had potent vasorelaxing effects on precontracted rat aortic
Purification of a cytotoxic crude alkaloid extract of Cassytha filiformis led to the isolation of four known aporphine alkaloids: neolitsine, dicentrine, cassythine (= cassyfiline) and actinodaphnine. Their structures were determined by analysis of spectroscopic data. All isolated alkaloids were
Cassytha filiformis (Lauraceae), a widely distributed parasitic plant, contains several aporphine alkaloids and is often used in African folk medicine to treat cancer, African trypanosomiasis and other diseases. In a previous investigation, we showed that the alkaloid plant extract and the isolated
