A New Additive for Reducing Free Radicals and Polycyclic Aromatic Hydrocarbons in Cigarette Smoke

For reducing the toxicity of PAHS and free radicals in cigarette smoke and tar, a new additive containing the pure Chinese herbal medicine was studied. Through the analysis with UV VIS and FLU, a kind of complex Chinese herbal medicine additive was chosen. The method of orthogonal experiment design was applied to the experiment arrangement and the optimum extract condition was obtained. The content of free radicals both in tar and in gas phase was determined by ESR and the content of PAHS in tar was determined by GC/MS. Experimental results show that the free radicals both in gas phase and in tar and the PAHS in tar have been markedly reduced by the additive.
