Abstract
Two new sarpagine-type indole alkaloids (1 and 2), together with five known alkaloids; 12-methoxy-4-methylvoachalotine (3), 16-demethoxycarbonylvoacamine (4), isositsirikine (5), affinisine (6), affinine (7), were isolated from the bark of Tabernaemontana macrocarpa Jack. The structures of these alkaloids were determined based on spectroscopic data, chemical correlation, and comparison with the literature. 16-Demethoxycarbonylvoacamine (4) showed antiplasmodial activities against Plasmodium falciparum 3D7 and cytotoxic activities against human cell line, HepG2 cells.
