Abstract
Two alkaloids, belonging to benzylisoquinoline alkaloids, were isolated from Annona squamosa. One of these alkaloids, 6, 7-dimethoxy-1-(alpha-hydroxy-4-methoxybenzyl)-2-methyl-1, 2, 3, 4-tetrahydroisoquinoline, was isolated for the first time from natural sources, while, the alkaloid, Coclaurine was known in Annona squamosa L. Moreover, the isolated alkaloids tested for the anti-cancer activities on various cell lines (HepG-2, MCF-7, and HCT-116).
