摘要
为比较贵州不同产区烤烟烟叶次生代谢物质含量,对道真、威宁、盘县、天柱和贵定5个产区的K326、云烟85、云烟87、贵烟1号和贵烟201等品种C3F和B2F等级的烤烟烟叶进行了分析。结果表明:①贵州烤烟烟叶中主要有机酸、多酚、生物碱、甾醇的平均含量分别为112.47,33.65,29.79和2.47 mg/g。②与国内其他产区烤烟烟叶相比,贵州烤烟烟叶有机酸、多酚和生物碱含量较高,甾醇含量居中。③贵州不同产区烤烟烟叶次生代谢产物主要成分总含量以盘县最高,威宁、天柱和道真次之,贵定最低;不同产区烤烟烟叶有机酸含量以盘县最高,多酚含量以威宁最高,生物碱含量以天柱最高。
In order to compare the secondary metabolite contents in flue-cured leaves from different areas in Guizhou Province, the leaf samples of C3F and B2F grades of K326, Yunyan 85, Yunyan 87, Guiyan 1 and Guiyan 201 varieties were collected from Daozhen, Weining, Panxian, Tianzhu and Guiding counties, and the secondary metabolite contents in the samples were analyzed. The results showed that： 1） The average contents of main organic acids, polyphenols, alkaloids and sterols were 112.47, 33.65, 29.79 and 2.47 mg/g, respectively. 2） The contents of organic acids, polyphenols and alkaloids in flue-cured tobacco leaves from Guizhou were relatively higher, while the contents of sterols were moderate comparing with those from other growing areas in China. 3） The total content of secondary metabolites in leaves from Panxian was the highest, followed by Weining, Tianzhu and Daozhen, while that from Guiding was the lowest. The highest organic acid content was found in leaves from Panxian, while the highest polyphenol content in leaves from Weining and the highest alkaloid content in leaves from Tianzhu.
