不同香型烟叶生物碱的差异规律
Alkaloids in Tobaccos of Different Aromatic Characteristics
摘要
Abstract
Alkaloids in tobaccos of different aromatic classifications were compared.Standard sampling method was employed to collect 543 flue-cured tobacco leaf specimens from 71 cities/counties in 15 provinces in China during 2011 and 2013.The samples were analyzed using the current industry methods,F-hypothesis testing,Q-clustering and discriminant analyses,as well as statistic methodology.The results showed that,between 2011 and 2012,the differences on the contents of and 2,3'-bipyridyl in the 3 categories of tobaccos were similar,and could be used for differentiating the varieties;while anabaseine found in 2013 was a characteristic substance that could be used to distinguish between the lightly and the strongly aromatic types of tobaccos.In those years,the 6 alkaloid compounds tested in the 3 categories of tobaccos could be clustered into 3 groups.By using the contents of nicotine,reduced nicotine,Mai Siming,anabaseine,,and 2,3'-bipyridine as indicators,the 3 aromatically different classifications of tobaccos could be identified with a discrimination rate of 55.7-71.6％ and an accuracy of 50.0-69.8％.关键词
