A new natural indole and three aporphine alkaloids from Monodora bevipes Benth. (Annonaceae)

Four compounds were isolated from the leaves of Monodora brevipes Benth. (Annonaceae). Among them, one new natural indole named 5-formylindole ( 1 ) and three known aporphine alkaloids: (+)-roemeroline ( 2 ); (+)-corydine ( 3 ) and (+)-menispermine ( 4 ). They were isolated for the first time from this species. The structures of these compounds were established according to their spectral data (NMR, SM, IR and UV).
