| 摘 要： | 以国内浓香型主产烟区的284份烤烟C3F为材料，采用偏相关分析、通径分析及逐步回归的分析方法，研究了浓香型烤烟中性致香成分及多酚含量与香气质量的关系。结果表明:中性致香物质和多酚类物质各指标对香气量、香气质的直接影响均不同；（1）香气质受6-甲基-5-庚烯-2-酮和绿原酸的直接正面影响最大，而受茄酮的直接负面影响最大，同时莨菪亭对其也有负面影响；（2）香气量受2-乙酰基吡咯和绿原酸的直接正面影响最大，而受苯乙醇的直接负面影响最大；（3）苯乙醛、糠醛、新植二烯、二氢猕猴桃内酯、巨豆三烯酮1、绿原酸、芸香苷对香气质和香气量均有直接正面影响；茄酮和藏花醛对香气质和香气量均有直接负面影响。因此，可通过调节调制条件提高中性致香物质和多酚物质中对香气质量有益成分，控制和降低对其不利的成分，改善其烟叶内在质量。, 以国内浓香型主产烟区的284份烤烟C3F为材料，采用偏相关分析、通径分析及逐步回归的分析方法，研究了浓香型烤烟中性致香成分及多酚含量与香气质量的关系。结果表明:中性致香物质和多酚类物质各指标对香气量、香气质的直接影响均不同；（1）香气质受6-甲基-5-庚烯-2-酮和绿原酸的直接正面影响最大，而受茄酮的直接负面影响最大，同时莨菪亭对其也有负面影响；（2）香气量受2-乙酰基吡咯和绿原酸的直接正面影响最大，而受苯乙醇的直接负面影响最大；（3）苯乙醛、糠醛、新植二烯、二氢猕猴桃内酯、巨豆三烯酮1、绿原酸、芸香苷对香气质和香气量均有直接正面影响；茄酮和藏花醛对香气质和香气量均有直接负面影响。因此，可通过调节调制条件提高中性致香物质和多酚物质中对香气质量有益成分，控制和降低对其不利的成分，改善其烟叶内在质量。

| Abstract: | Taking 284 strong aroma type flue-cured tobacco leave ranked C3F in China as samples to investigate the relationship between neutral aroma constituents and polyphenol material content and concentration and quality of aroma by analytical methods of partial correlation analysis, path analysis and stepwise regression. (1) The quality of aroma was directly positive influenced by 6-methyl-5-heptene-2-ketone and chlorogenic acid greatly, and was directly negative influenced by solanone greatly, and it was negative influenced by scopoletin; (2) The concentration of aroma was directly positive influenced by 2 - acetyl pyrrole and chlorogenic acid greatly, and was direct negative influenced by phenethyl alcohol greatly;(3) The quality and concentration of aroma were directly positive influenced by hyacinthin, furfural, neophytadiene, dihydroactinidiolide, Megastigmatrienone, chlorogenic acid, rutin; and were directly negative influenced by solanone and safranal. Therefore, adjusting the curing conditions could increase the composition in neutral aroma constituents and polyphenol material which were beneficial for the quality and concentration of aroma, control and decrease the harmful composition, and then improve the interior quality of tobacco leave., Taking 284 strong aroma type flue-cured tobacco leave ranked C3F in China as samples to investigate the relationship between neutral aroma constituents and polyphenol material content and concentration and quality of aroma by analytical methods of partial correlation analysis, path analysis and stepwise regression.
