Abstract
From leaves, root - and stem - barks of Annona muricata L., seven isoquinoline alkaloids have been isolated: reticuline (main alkaloid), coclaurine, coreximine, atherosperminine, stepharine. Anomurine and anomuricine, two minor alkaloids, are new tetrahydrobenzylisoquinolines, with 5, 6, 7 substituted ring A. The phytochemical significance of these alkaloids is discussed.
