Abstract:

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 and 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 analysis and chemical composition of the smoke was analysis quantitatively and qualitatively by using the GC-MS. Compared with the blank sample, the magnolia compound filter tip cigarettes have the effect of lowering the content of nicotine, total particulate matter and tar, and the reduction rate was 8.14%, 12.62% and 14.54%. Also these cigarettes have an obvious effect on the retention of some of the harmful ingredients of cigarette smoke particularly the phenolic substances which are carcinogenic and cancer-promoting. Phenol, p-cresol, 4-ethylresorcinol and 2,2'-methylene bis-(4-methyl-6-tert-butyl-phenol) reduced by 56.8%, 32.8%, 50% and 29.0% respectively. The results showed that cigarette filters added with Magnolia Biondii Pamp can effectively reduce the harmful components of the smoke and they are in line with the direction of "Chinese cigarettes" development.
