    Author: Lim KH, Thomas NF, Abdullah Z, Kam TS.
    Journal: Phytochemistry; 2009 Feb; 70(3):424-9. PubMed ID: 19217125.
    Abstract:
    Two seco-tabersonine alkaloids, jerantiphyllines A and B, in addition to a tabersonine hydroxyindolenine, jerantinine H, and a recently reported vincamine alkaloid 7, were isolated from the leaf extract of the Malayan Tabernaemontana corymbosa and the structures were established using NMR and MS analysis. Biomimetic conversion of jerantinines A and E to their respective vincamine and 16-epivincamine derivatives were also carried out.
