摘　　要：采用四甲基偶氮唑盐比色(MTT)法观察杨树芽提取物对MCF-7、SMMC-7721和A549 3种肿瘤细胞的体外生长抑制作用,并与市售蜂胶和杨树胶的抗肿瘤活性进行对比。结果表明:杨树芽提取物对3种肿瘤细胞作用48 h的抑制率分别为97.1%、88.7%和60.5%,半数抑制质量浓度(IC50)分别为58.4、83.9和196.3 mg/L,均高于蜂胶和杨树胶。杨树芽提取物对体外培养的肿瘤细胞生长有明显的抑制作用,提示杨树芽提取物具有良好的抗肿瘤活性。The growth-inhibition effect of poplar bud extract on MCF-7, SMMC-7721 and A549 cell lines by MTT assay were observed and the anti-tumor activity was compared with propolis and poplar gum from market. The results showed that the inhibitory rates of poplar bud extract on the three cell lines for 48 h, were 97.1%, 88.7 % and 60.5 % , with the ICs0 of 58.4, 83.9 and 196.3 mg/L, respectively, which were higher than those of propolis and poplar gum. Poplar bud extract has significantly inhibited the growth in vitro on the three cell lines, suggesting that poplar bud extract has obvious anti-tumor activity.
