摘要
Abstract
For reducing the content of benzo[α]pyrene（B[α]P） in the mainstream cigarette smoke（MSS）,a novel filter additive containing the plant alkaloid was studied.Coptis alkaloids were extracted from rhizome of coptis chinensis,which contained a lot of the quaternary ammonium hydrate with isoquinoline structure.The interactions of coptis alkaloids with B[α]P was investigated by fluorescence quenching.The way of adding coptis alkaloids in the cigarette filter to reducing B[α]P were discussed.The results showed that the correlation coefficients of coptis alkaloids and B[α]P were 0.981～0.998,and the binding constants were（2.0～9.0）×103,more than 20% of B[α]P were eliminated from MSS,with greater reductions when more coptis alkaloids were added in the filter.With the same mass of coptis alkaloids in the filter,the reduction trend for B[α]P was palmatine〉coptis total alkaloids〉berberine〉coptisine.Comparing with the control cigarette,the content of B[α]P in the mainstream smoke of cigarette with palmatine in modified filter were reduced by 25.16%,when the filter containing 120mg/g of palmatine carried by 15mg/cig of activated carbon fiber.关键词
