部分国产烤烟样品挥发碱含量的比较

Compare Analysis of Volatile Alkaloid of Some Domestic Fluecured Tobacco Leaves

为比较不同地区不同烟叶挥发碱含量的差异,测定了福建、贵州、四川、山东、河南、云南、辽宁、重庆、湖南等不同地区,不同等级的共182种烟样的挥发碱含量,进一步验证了不同产区,以及不同烟叶部位、不同等级的烤烟烟叶的挥发碱含量均差异显著,挥发碱含量随烟叶部位变化规律明显,挥发碱含量均随烟叶等级的升高而降低等。聚类分析结果同样显示不同地区烟叶间存在一定的差异性。

The volatile alkaloid contents of one hundred eighty-two kinds of fluecured tobacco from Fujian, Guizhou, Sichuan, Shandong, He＇nan, Yunnan, Liaoning, Chongqing and Hunan were studied and compared. The analytic data showed that of the upper leaves were higher than that of the middle leaves and higher than that of the lower/eaves. In the same stalk position, the better the quality was the higher the content of the volatile alkaloid. The results showed that the content of the volatile alkaloid was significant difference in the different varieties, stalk position and in the different areas. The data clustered by quick clustering algorithm （QCA） also showed the same results. A reference basis was provided for studying the quality characteristic, and properly using in the cigarette blending design of every grade tobacco leaf.
