RESULTS:Isoalantolactone exhibited excellent anti-proliferative activities on HeLa, SHIN3 and HOC-21 and HAC-2 cell lines, while 1-O-acetylbritannilactone and britannilactone demonstrated weak anti-proliferative activities on HeLa, SHIN3, HOAC-21 and HAC-2 cell lines even at the concentration of 100 μmol/L. The apoptotic rate in isoalantolactone group with the concentration of 12.5 μmol/L was higher than that in PBS group.

结果： 异土木香内酯对上述5种肿瘤细胞的增殖均有明显的抑制作用，1-氧-乙酰大花旋覆花内酯和大花旋覆花内酯即使在100 μmol/L的高浓度下，对5种妇科肿瘤细胞的增殖不显示抑制活性；流式细胞学检查发现异土木香内脂处理后的HeLa细胞出现凋亡现象。
