title: Three new megastigmanes from the leaves of Annona muricata.
abstract: Three new megastigmanes (1-3), named annoionols A and B (1, 2) and annoionoside (3), were isolated from the leaves of Annona muricata L. (Annonaceae) together with 14 known compounds (4-17). Among the known compounds, annoionol C (4) was isolated from a natural source for the first time. The structures of all compounds were elucidated by spectroscopic and chemical analyses.
