瑞香狼毒总黄酮提取物的抗肿瘤作用

目的:　研究瑞香狼毒总黄酮提取物的抗肿瘤作用。方法:体外抗肿瘤活性研究采用MTT比色法和集落形成法测定,靶细胞采用人胃癌细胞SGC- 790 1、人肝癌细胞BEL- 74 0 2和人白血病细胞HL- 6 0 ;通过提取物对小鼠的移植性肿瘤S180和H2 2生长的影响来评价体内抗肿瘤作用。结果:瑞香狼毒总黄酮提取物对体外培养的肿瘤细胞有较强的抑制作用,体外抗肿瘤活性高于长春新碱;瑞香狼毒总黄酮提取物急性毒性较小,对小鼠移植性肿瘤S180和H2 2的生长也有显著的抑制作用,并和剂量正相关,高剂量组对小鼠移植性肿瘤S180的抑制率为4 5 . 6 4 % ,H2 2的为4 7 .5 9% ,与阳性对照组环磷酰胺的抑制率接近。结论:瑞香狼毒总黄酮提取物具有较强的体内和体外抗肿瘤作用。

The antitumor effects of total-flavonoid from Stellera chamaejasmel

Objectove: To study the antitumor effects of total-flavonoid from S. chamaejasmel. Method:The in vitro antitumor activity against human cancer cell lines, such as stomach cancer SGC-7901, hepatocarcinoma BEL-7402 and leukemia HL-60, were determined by a MTT and clone formation assay. The in vivo antitumor activity was evaluated by the antitumor bioassay against transplanted mouse solid tumor S180 and H22. Result: The total-flavonoid inhibited cell proliferation of human tumor cell lines, and its activities are higher than that of vincristine. The total-flavonoid also showed a lower acute toxicity and the strong antitumor activity against transplanted mouse solid tumor S180 and H22 in vivo showing a positive correlation with the concentration. The inhibitory rates at the dose of 0.10 g·kg^-1 ip against S180 and H22 are 45.64% and 47.59%,respectively. Conclusion:The total-flavonoid from S. chamaejasme has antitumor activities in vivo and in vitro.
