摘要 采用蚕豆根尖细胞微核检测技术,分析测定不同茶类抗香烟烟雾水溶物诱变的效果.结果表明,各茶类茶叶都具有明显降低香烟烟雾水溶物诱发细胞微核率的作用,抗诱变效果为绿茶、乌龙茶明显优于白茶、红茶,而绿茶与乌龙茶及白茶与红茶之间差异不大;各茶类1∶50 茶水比抗诱变能力强于1∶100 茶水比;抗诱变效果与茶叶中儿茶素含量高低呈正相关.由此提示饮茶可能是吸烟与被动吸烟者抗烟毒的有效途径之一. Different tea was added to water soluble substance containing cigarette smoke and the effects were analysed by testing cellular micronuclei of root tip cells of Vicia faba . The results showed that the cellular micronuclei frequency decreased significantly. Green tea and Oolong tea were more effective than white tea and black tea, but there was less difference between green tea and Oolong tea, so as white tea and black tea. At the same time, the tea liquid/water ratio of 1/50 was also more effective than that of 1/100. The effects were positively correlated with catechins. It could be deduced that drinking tea could control the harm from cigarette smoke.
