摘　　要：从紫玉盘(Uvaria microcarpa)种子中首次分离得到二个白色蜡状固体,经光谱分析鉴定:一个为新的番荔枝内酯-紫玉盘素 B(Microcarpacin B),一个为已知的番荔枝内酯-Rollinicin。Microcarpacin B(1),a novel adjacent bis-tetrahydrofuranyl annonaceous acetogenin was isolated from the alcoholic extracts of the seeds of Uvaria microcarpa champ.Benth,Its structure was elucidated based on spectroscopic methods. In addition to the new one, a known potent cytotoxic acetogenin,Rollinicin(2) was also isolated from the same plant source.
