摘要: 目的: 探讨绿茶、茶多酚、半枝莲、白花蛇舌草及犀黄丸等的水溶性提取物对苯并芘[B(a)P]和4-甲基亚硝胺基-1-(3-吡啶基)-1-丁酮(NNK)的抗诱变作用。 方法: 采用沙门氏菌回变试验(Ames试验)。 结果: 除各受试物的最小剂量组外,其它浓度的绿茶、茶多酚、半枝莲、白花蛇舌草及犀黄丸等均具有明显的抑制B(a)P和NNK诱发TA 98和TA 100回复突变的作用。经统计学处理,各试验组与对照组比较有显著性差异(P<0.01)。 结论: 受试的中草药和绿茶对B(a)P和NNK均有抗突变作用,且存在剂量反应关系。

Abstract: Purpose: To investigate the antimutagenicity of water extract of green tea, tea polyphenol, Scutellaria barbata D. Don, Hedyotis diffusa wildi and Xihuangwan to benzoapyrene[B(a)P] and 4-methylnitrosamino-1-(3-pyridy)-1-butanone(NNK). Methods: The Ames test was used in this study. Results: Except the lowest dosage group, all the other dosage groups of green tea, tea polyphenol, Scutellaria barbate,Hedyotis diffusa wildi and Xihuangwan inhibited the reverse mutation of TA 98 and TA 100 induced by B(a)P and NNK significantly(P<0.01). Conclusion: The tested Chinese herbal medicines and green tea have antimutagenicity to B(a)P and NNK, and there is a dose-effect relationship.
