我国不同生态烟区烤烟的部分化学成分和多酚类物质含量的比较

Comparison on the Partial Chemical Composition and Polyphenols Content of the Flue-cured Tobacco from Different Ecology Smoke Area in Our Country

对我国5个主要烟区的3个等级烟叶标样的多酚类物质和主要化学成分进行了系统的比较和评价。结果表明:云南和贵州两地多酚含量较高,烟碱含量中等,总糖、还原糖的含量相对较高。安徽烟区烟碱含量略高。辽宁和安徽烟叶的多酚、总糖和还原糖含量普遍较低。辽宁、安徽烟区烟叶糖碱比较低,烟叶协调性不够;云南和贵州烟区的各部位烟叶协调性普遍较好。

This article has carried on the comparison of polyphenols material and the main chemical composition of the tobacco leaf of the 5 main areas in our country. The result indicated ： The polyphenol content of Yunnan and Guizhou tobacco is higher than that of others. The nicotine content is medium. The total sugar and the return sugar content are relatively higher than that of others. The nicotine content of Anhui area is slightly high. The polyphenol, the total sugar and the return sugar content of Liaoning and Anhui tobacco leafs are generally low. The coordination of leaf tobacco of Liaoning and Anhui are bad, while the Yunnan and Guizhou tobacco＇s are generally good.
