摘要
目的:研究薰衣草乙醇提取物对人肺癌细胞A549、肝癌细胞SMMC7721的生长抑制作用。方法:分别用HE染色法和溴化二苯偶氮盐(MTT)检测法,观察其形态学变化和对肿瘤细胞的增殖抑制作用。结果:显微镜下可见A549、SMMC7721形态明显改变,200 mg/mL马力诺薰衣草提取物作用48 h时,其抑制率分别为(79.61±4.40)%,(81.05±5.16)%。结论:薰衣草对A549、SMMC7721细胞均有抑制作用,且呈量效关系。
Objective： To investigate the cytotoxic effect of Lavender angustifolia extract on human lung carcinoma A549 and hepatoma SMMC7721. Method： The morphology was observed with HE staining, the inhibitory effect on cell proliferation of A549 and SMMC7721 was used MTT assay. Result：The morpHology of A549 and SMMC7721 significantly changed under light microscope. The inhibitory rate is （79.61 ± 4.40）% and （81.05±5.16）%, respectively for A549 and SMMC7721 at 48h at the concentration of 200mg/mL. Conclusion：The extract of Lavender angustifolia had inhibitory effect on the proliferation of A549 and SMMC7721, the effect was dose dependent.
