云南不同生态烟区烤烟主要挥发性香气物质含量的比较

 以云南不同生态区烤烟云烟85烟叶为材料，采用气质联用仪对烤烟主要挥发性香气物质含量进行了分析。结果表明：6个烤烟种植区烟叶挥发性香气成分中仅二氢猕猴桃内酯、金合欢基丙酮、新植二烯含量不存在极显著差异，其余挥发性香气成分均存在显著性地区差异。滇东北地区烤烟芳香族氨基酸降解产物、美拉德反应物、类胡萝卜素降解产物和新植二烯含量最高，滇西南地区西柏烷类化合物含量最高。

Comparison on the Main Volatile Aroma Components of Flue cured Tobacco from Different Ecological Regions in Yunnan Province

Volatile aroma components of tobacco leaves after flue curing from Yunyan 85 among different Yunnan tobacco planting areas were analyzed with the method of gas chromatography mass spectrometry (GC MS). The results indicated that: there were not significant differences in the flue cured tobacco of dihydroactinidiolide, farnesy lacetone, neophytadiene among six Yunnan tobacco areas, but there were significant regional differences in other volatile aroma components. The tobacco leaves from the northeast Yunnan had the highest content of aromatic amino acid degradation products, maillard reaction products, carotenoids degradation products and neophytadiene, the tobacco leaves from the southwest Yunnan had the highest content of cembrane degradation products.
