辛夷滤嘴降低卷烟烟气中的有害成分研究

Study of Magnolia Biondii Pamp Filter on Reducing the Harmful Constituents of Cigarette Smoking

为研究辛夷滤嘴降低卷烟烟气中有害成分的作用,采用对比分析方式,先用吸烟机捕集卷烟烟气,收集主流烟气的总粒相物,再用超声波萃取方法对收集烟气粒相物的剑桥滤片进行萃取,分析烟气中的常规成分(烟碱、焦油、水分),最后用GC/MS定量、定性分析烟气化学成分。结果表明,与空白样对比,辛夷滤嘴卷烟对烟碱、总粒相物、焦油量有降低作用,且分别降低了8.14%、12.62%和14.54%;对烟气中的一些有害成分,特别是促癌、致癌的酚类物质的截留效果比较明显,苯酚降低56.8%,对甲苯酚降低32.8%,4-乙基间苯二酚降低50%,2,2'-亚甲基双-(4-甲基-6-叔丁基苯酚)降低-29.0%。添加辛夷的卷烟滤棒能有效的降低烟气中的有害成分,符合"中式卷烟"的发展方向。

To study the effect of magnolia filter on reducing the harmful ingredients in cigarette smoking,Magnolia Biondii Pamp.Filter tip cigarettes and the blank samples were analyzed.Cigarette smoke was trapped with the smoking machine the total particulate matter of the mainstream smoke was collected,then the Magnolia Biondii Pamp.Filter which contained particulate matter of the smoke was extracted with ultrasonic extraction system.After that,conventional composition of the smoke（nicotine,tar,water）was analyzed and chemical composition of the smoke was analyzed quantitatively and qualitatively by using the GC-MS.The results showed that the magnolia compound filter tip cigarettes could reduce the content of nicotine,total particulate matter and tar,and compared with the blank sample and the reduction rate was 8.14%,12.62%and14.54%.Respectively.Another these cigarettes had an obvious effect for the retention of some harmful ingredients from cigarette smoking particularly the phenolic substances which are carcinogenic andcancer-promoting.Phenol,p-cresol,4-ethylresorcinol and 2,2＇-methylene bis-（4-methyl-6-tert-butyl-phenol）were decreased by 56.8%,32.8%,50%and 29.0%respectively.The cigarette filters added with Magnolia Biondii Pamp can effectively reduce the harmful components of smoke.This result would agree with the direction of＂Chinese cigarettes＂development.
