摘　　要：以湖南和云南8个不同产区的C3F烤烟叶为材料,采用同时蒸馏萃取和气相色谱法对不同产区烤烟的挥发和半挥发性有机酸含量进行分析。结果表明:(1)云南和湖南挥发酸含量差异较大,绝大多数挥发酸在云南含量明显高于湖南,而半挥发酸含量差异较小,且在云南的含量要略低于湖南;(2)云南4个产区烤烟烟叶中绝大多数挥发酸在曲靖和文山的含量明显高于昭通和昆明,且含量差异显著,而半挥发酸除十四酸外,其他半挥发酸及其总量均表现出曲靖最高,文山次之,昆明最低,且含量差异显著;(3)湖南4个产区烟叶中除丁酸差异不显著外,其他绝大多数挥发酸含量产区差异较大,但产区间差异无明显规律;半挥发酸除十四酸外其他绝大多数半挥发酸及其总量均以慈利含量最高,邵阳最低,且产区间含量差异显著。C3F flue-cured tobaccos come from different production regions in Yunnan and Hunan were used for this study, the content of volatile and semi-volatile acid in flue-cured tobacco were studied by simultaneous distillation and extraction and gas chromatography. The results indicated that： （1） the content of volatile acid in Yunnan and Hunan existed greatly difference, but the content of semi-volatile acid differed little between the Yunnan and Hunan. Most content of volatile acid in Yunnan were all richer than those in Hunan, but the content of semi-volatile acid contrarily. （2） Most content of volatile acid in Qujing and Wenshan were significantly higher than those in Kunming and Zhaotong. The content of semi-volatile acid （except tetradecanoic acid） of Qujing was the highest, followed by Wenshan, while the Kunming was the lowest,and the difference was obviously. （3） Most content of volatile acid （except butyric acid） were significantly different among the different production regions in Hunan, but the difference had no obvious regularity. Most content of semi-volatile acid （except tetradecanoic acid） of Cili were the highest, while the Shaoyang were the lowest, and the difference was obviously.
