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
从马来亚 Tabernaemontana corymbosa 的叶提取物中分离出两种 seco-tabernaemontana 生物碱,jerantiphyllines A 和 B,以及一种 tabersonine hydroxyindolenine、jerantinine H 和最近报道的长春胺生物碱 7,并使用 NMR 和 MS 分析建立了结构. 还进行了 jerantinines A 和 E 到它们各自的长春胺和 16-表春胺衍生物的仿生转化。
