复合添加剂降低卷烟烟气中多种致癌物研究

Reducing Carcinogenic Compounds in Cigarette Smoke by Rhodeopteridium Extract

为研究降低卷烟烟气中多种致癌物的方法 ,从羊齿类天然植物中提取出多种酮、酚类及其衍生物组合得到复合添加剂 ,以 0 0 0 8%的比例添加于卷烟滤嘴或烟丝中。检测结果表明 ,在卷烟中添加该复合添加剂后 ,其主流烟气中的多种稠环芳烃、自由基和芳香胺等致癌物的含量显著降低 ,对烟气中烟草特有亚硝胺也有一定的清除作用。

In order to reduce carcinogenic compounds in cigarette smoke,the extract from rhodeopteridium plant was added into filter or cut rags at 80ppm.The results of smoke analysis indicated that the polycyclic aromatic hydrocarbons,free radicals and aromatic amines in cigarette mainstream smoke were significantly reduced and tobacco specific N-nitrosoamines were eliminated to a certain extent.
