- 中文摘要: Thirty-five compounds including twenty-one alkaloids, lysicamine (1), liriodenine (2), atherospermidine (3), oxoxylopine (4), oxoanolobine (5), oxoglaucine (6),(-)-anonaine (7), (-)-asimilobine (8), (-)-xylopine (9),(-)-anolobine (10), (-)- norisocorydine (11),(+)-laurotetanine (12), (+)-isocorydine (13),(-)-N-methylasimilobine (14), (+)-N-methyllaurotetanine(15), (-)-norushinsunine (16), (-)-ushinsunine (17),(-)-N-formylanonaine (18), (+)-stepharine (19),(+)-orentaline (20), and (-)- kikemanine (21); four kauranes, ent-kaur-16-en-19-oic acid (22), 16.beta.-hydroxy-17- acetoxy-ent-kauran-19-al (23), 17-acetoxy-16.beta.-ent- kauran-19-oic acid (24), and 16.beta.-hydroxy-17-acetoxy- ent-kauran-19-oic acid (25); two amides, N-trans- feruloyltyramine (26), and N-trans-caffeoyltyramine (27); one purine, adenosine (28); one lactam amide, squamolone(29); and six steroids, .beta.-sitosterol (30), stigmasterol (31), .beta.-sitostenone (32), stigmasta-4,22- dien-3-one (33), 6.beta.- hydroxy-.beta.-sitosterone (34), and 6.beta.-hydroxystigmasterone (35) are isolated from the stems of Annona cherimola. These compounds were characterized and identified by physical and spectral evidence. Among them, (-)-norisocorydine (11) was elucidated as a new enantiomer with a levorotary configuration, which is isolated for the first time.
