目的探讨中药虎杖的主要药用成分白藜芦醇的抗直肠腺癌的机制。方法不同浓度的白藜芦醇作用于人结直肠腺癌HCT-15细胞后，用显微镜观察人结直肠腺癌细胞的形态学改变；细胞计数试剂盒（CCK-8）检测白藜芦醇对细胞增殖的影响；Westernblot法检测白藜芦醇对人结直肠癌细胞凋亡相关指标的影响；裸鼠移植瘤模型实验观察白藜芦醇的体内抑制肿瘤生长的活性。结果显微镜观察结果显示虎杖的药用成分白藜芦醇作用后细胞数量减少，细胞间距增大，细胞皱缩。0、50、100μmol／L的白藜芦醇处理24h后，HCT-15细胞的存活率分别为100％、68％和39％。白藜芦醇作用能够抑制癌细胞增殖，诱导癌细胞死亡的半数致死量为72μmol／L。Western blot结果显示白藜芦醇诱导人结直肠腺癌细胞凋亡主要是通过线粒体途径，如细胞色素C释放及凋亡蛋白半胱氨酰天冬氨酸特异性蛋白酶（Caspase）-3剪切。裸鼠实验结果表明白藜芦醇可有效缩小体内肿瘤的体积，0、50、100μmol／L的白藜芦醇对肿瘤的抑制率分别为0．0％、43．6％、68．6％。结论白藜芦醇在体外对人结直肠腺癌细胞增殖具有明显抑制作用，其机制主要是促进肿瘤细胞凋亡，白藜芦醇能有效的抑制体内肿瘤的增长。
