摘要
对21个品牌的国内外卷烟中5种主要的非挥发性有机酸及5种主要的高级脂肪酸进行定量分析。结果显示，国外混合型卷烟的非挥发有机酸的总含量从107．9mg／g至120．4mg／g，平均值为114.5mg／g，国内烤烟型卷烟从85．3mg／g至132．3mg／g，平均值为109．6mg／g。国外混合型卷烟的草酸、柠檬酸平均含量分别为28和23．5mg／g，而国内的烤烟型卷烟仅为21．8和7．8mg／g；国外混合型卷烟的苹果酸平均含量60．0mg／g，而国内的烤烟型卷烟高达77．8mg／g；英式烤烟型卷烟的情形介于中间。高级脂肪酸的含量，国内的烤烟型卷烟明显高于国外混合型卷烟，而英式烤烟型卷烟的情形仍介于中间。
Five nonvolatile organic acids and five major high fatty acids in 23 brands of domestic and foreign cigarettes were determined. The acids were derived into methyl esters by sulfuric acid - methanol(7:100, v/v)and extracted with dichloromethane, then analyzed by capillary gas chromatography. The results showed that, total levels of nonvolatile organic acids in foreign cigarettes (American blend ) were rangedfrom 107. 9 to 120. 4 mg/g, with the mean value at 114. 5mg/g; While those of domstic brands (Virginia blend ) were ranged from 85. 3 to 132. 3 mg/g, and with the mean value at 109. 6mg/g. The mean levels of oxalic, citric and malic acid in foreign cigarette were 28, 23. 5 and 60 mg/g, respectively; while those of domestic brands were 21. 8, 7. 8 and 77. 8mg/g, respectively. The situation of British style Virginia blend was at medium between above two type of cigarettes. Levels of high fatty acids in domestic cigarettes were higher than those in foreign cigarettes, while those of British style Virginia blend was also at the medium.
