摘　　要：为研究湖南不同产区烤烟糖和有机酸含量的差异对烟叶香气风格形成的影响,采用气相色谱法,对湖南4个不同产区郴州、邵阳、凤凰和慈利烤烟中部叶的糖和有机酸含量进行分析。结果表明:凤凰与邵阳的总糖和还原糖含量明显高于慈利和郴州,但非挥发酸含量却恰恰相反。4个产区烟叶中非挥发酸、挥发酸和有机酸总量均以慈利最高,郴州次之,凤凰最低,但凤凰的高级脂肪酸总量最高且与其他产区之间差异极显著;除丙二酸外,其他非挥发酸含量差异均达极显著水平;异丁酸、戊酸和3-甲基戊酸含量在产区间差异极显著,而丁酸差异不显著,其他绝大多数挥发酸含量产区差异较大,但4个产区间差异没有规律;慈利、凤凰和郴州这3个产区烟叶中的高级脂肪酸含量差异不大,但邵阳与这3个产区之间除肉豆蔻酸外其他成分含量差异均达显著水平。In order to investigate the effects of differences which the content of sugar and organic acids in flue-cured tobacco in different areas of Hunan on aromatic style, using gas chromatography, the difference and itspertinence analysis of the content of sugar and organic acids in middle leaf of flue-cured tobacco at the Hunandifferent areas were studied. The different areas included Fenghuang, Chenzhou, Cili and Shaoyang. Resultsindicated that： The content of soluble total sugar and the return to original state sugar in Fenghuang andShaoyang were significantly richer than Cili and Chenzhou, but the non volatile acid was quite the opposite. In4 flue-cured tobacco regions, the content of total non-volatile acid, volatile acid and organic acids in Cili werehighest, followed by Chenzhou, Fenghuang was the lowest, but Fenghuang contained the highest total seniorfatty acids, and with the other areas existed higher difference. The majority content of non-volatile acids exitedremark difference except malonic acid. In 4 flue-cured tobacco regions, the content of isobutyric acid, valericacid and 3-methyl pentanoic acid existed remark difference but butyric acid was not notable. The othersexisted difference but the difference of four productions existed no laws. The content of senior fatty acids inthree tobacco production regions of Cili, Chenzhou and Fenghuang existed small difference, but with theShaoyangexistedhigher difference except myristic acid.
