Three new Annonaceous acetogenins, (2,4-cis and trans)-9-hydroxy asimicinone (1), (2,4-cis and trans)squamoxinone B (2) and (2,4-cis and trans) squamoxinone C (3), were isolated from the bark of Annona squamosa with the help of countercurrent chromatography. Additionally found was isoannoreticuin (4
