Abstract: Established a new method for determination of volatile phenols in tobacco &cigarette extracts by continuously flow analysis, The sample extracted by water is distillated under the 155℃ condition ,and the distillation medium is 16%(v/v)H3PO4.The volatile phenols reacts with 4-antipryrine and potassium ferricyanide, the pink reactant is measured using Continuously Flow Analysis method. Beer`s law is obeyed over the concentration range of 0 mg/l—6 mg/l of phenol, the linear relationship is 0.9996, the detection limit(s/n=3) is 3.9ug/l, the average recovery is 98.5%-101.1%, and the relative standard deviation(RSD)is 1.9%(n=10).
