摘　　要：该研究以对甲苯磺酸为甲酯化催化剂,对甲酯化的各种条件进行优化,采用气相/质谱法对烟草薄片中的多元有机酸含量进行测定。试验结果表明,采用该方法法重复测定的变异系数较小,平均回收率在96.26%~103.37%,具有较好的重现性和准确性,适用于烟草薄片中多元有机酸含量的测定。The p-toluene sulfonic acid was used as esterification catalyst and the methyl esterification conditions ofpolybasic acids were optimized,polybasic acids contents in tobacco sheet were determined by gas chromatographymass spectrometry method.The results showed the method had good reproducibility and accuracy,the less variationcoefficient and the average recovery ratio was 96.26%-103.37%.The method can be used to determine the polybasicacids in tobacco sheet.
