Two new alkaloids from artabotrys uncinatus
A novel oxazoloaporphine, artabonatine A (1), and a new 7-hydroxyaporphine, artabonatine B (2), have been isolated and characterized from the fresh unripe fruits of Artabotrys uncinatus, along with five known compounds. Structure elucidation of 1 and 2 was based on UV, IR, NMR, and MS analyses.
