Aspidosperma pyricollum

Ajmalicine (139a) and 3-isoajmalicine (140a) were both converted to oxindole alkaloids, mitraphylline (167) and isomitraphylline (168) in Mitragyna parvifolia (Roxb.) Korth. (Rubiaceae)(S4). Feeding experiments on Vinca minor Linn. (Apocynaceae) had shown that vincamine (169) is biosynthesized via geissoschizine, stemmadenine, secodine, and tabersonine (85). Apparicine (170), which lacks one carbon atom of the tryptamine side chain, appears to be derived in Aspidosperma pyricollum Miiell. Arg. (Apocynaceae) from stemmadenine (86). [Pg.580]
