-
摘要: 自喜树(Camptotheca acuminata Decne)果中分到一个新生物碱,经光谱分析(UV,IR,1HNMR,MS,CD)推定为18-羟基喜树碱(Ⅰ),同时分得的还有吕宋果内酯,水杨酸和壬二酸。18-羟基喜树碱对P388白血病细胞有细胞毒活性。Abstract: A new alkaloid 18-hydroxycamptothecin, along with strychnolactone, salicylic acid and nonandioic acid was isolated from the seeds of Camptotheca acuminata Decne(Nyssaceae). shows a strong cytotoxility against P 388 leukemia cell in vitro.
