摘要 对傣药铁刀木Cassia siamea叶的化学成分进行研究。运用硅胶、凝胶、MCI-gel树脂及RP-HPLC等多种色谱技术从铁刀木叶90%乙醇提取物中分离鉴定了1个异吲哚生物碱类化合物,鉴定为5-(羟甲基)-2-甲基-6-异戊烯基^(-1)-酮(1)。生物活性测试中,其对NB4,A549,SHSY5Y,PC3,MCF7的IC_(50)分别为3.2,4.6,2.8,6.4,2.5μmol·L^(-1)。化合物1为新化合物,并且表现出一定的细胞毒活性。 A new isoindole alkaloid( 1),has been isolated from the leaves of Cassia siamea by using various chromatographic techniques. Compound 1 is a new compound,determined as 5-( hydroxymethyl)-2-methyl-6-prenylisoindolin-1-one,and it displayed cytotoxicity against NB4,A549,SHSY5 Y,PC3 and MCF7 cell lines with IC_(50) values of 3. 2,4. 6,2. 8,6. 4,2. 5 μmol · L-(- 1),respectively.
