Active plant metabolites have been used as prototype drugs. In this context, Tabernaemontana catharinensis (Apocynaceae) has been highlighted because of the presence of active indole alkaloids. Thus, this study aims the bio-guided search of T. catharinensis cytotoxic alkaloids. The chemical
The present work aimed to analyze the alkaloid content of the ethanolic extract of Tabernaemontana catharinensis (Apocynaceae family) and its fractions as well as to evaluate their antioxidant and anticholinesterasic activities. The analyses of the ethanolic extract of T. catharinensis by mass
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
