Alkaloids of Toddalia asiatica (Rutaceae)

Abstract Phytochemical investigation of the alkaloidal extract of the roots of Toddalia asiatica led to the isolation of a new seco-benzophenanthridine alkaloid (1) and twelve known alkaloids (2–13). The new structure was elucidated by means of spectroscopic analysis, and the known alkaloids were identified by comparison with the literature. Among these alkaloids, 1 and 5–7 were reported from the genus Toddalia for the first time. The distribution of the isolated alkaloids at genus/family level was presented via network analysis and their chemotaxonomic significance was also discussed.
