| 摘 要： | 在湖南省桂阳烟区选择K326、云烟87、YZ206-9、湘烟3号4个烤烟品种,测定它们的化学成分和中性致香物质含量。结果显示:云烟87的总糖、还原糖和淀粉含量最高(30.26%、28.11%、4.74%),K326的烟碱含量(3.00%)最高,湘烟3号的总氮最高(2.16%),YZ206-9的石油醚提取物最高(5.46%)。4个烤烟品种烟叶除总糖、还原糖和氯含量均超出优质烤烟标准范围,其他化学成分含量均符合优质烟叶的标准。氮碱比和糖碱比也在优质烟叶范围,但钾氯比低于优质烟叶的标准。品种间烟叶的中性致香物质的种类一致,但含量差异显著。云烟87的中性致香物质总量以及大部分质体色素降解产物、美拉德反应产物、苯丙氨酸类降解产物含量都最高,显著高于其他品种。K326的类西柏烷类产物含量最高,显著高于云烟87和湘烟3号。湘烟3号与K326大部分美拉德反应产物和苯丙氨酸类降解产物含量相近,差异不显著。YZ206-9美拉德反应产物和苯丙氨酸类降解产物含量普遍低于其他品种。不同烤烟品种的化学成分和中性致香物质所占比例不同,含量也有较大差异。

| Abstract: | s: Varieties K326, Xiangyan3, Yunyan87 and YZ206-9 were selected in Guiyang tobacco-growing area of Hunan province to determine the chemical composition and neutral aroma substances in tobacco leave. The results showed the content of total sugar, reducing sugar and starch in Yunyan87 was the highest (30.26%, 28.11%, 4.74% respectively), K326 had the highest content of nicotine (3.00%),Xiangyan 3 had the highest content of total nitrogen (2.16%), YZ206-9 had the highest content of petroleum ether extract (5.46%). Chemical components contents in leaves from 4 varieties of flue-cured tobacco are in line with standards of quality tobacco except for total sugar, reducing sugar and chlorine content which exceeded the standard range of high quality tobacco. The ratio of nitrogen to nicotine and the ratio of sugar to nicotine are in the range of high quality tobacco, while the ratio of potassium to chlorine was below the standard of high quality tobacco. The varieties of neutral aroma constituents in leaves from 4 varieties of flue-cured tobacco were the same, but the contents of which showed significant difference. The total amounts of neutral aroma substances, the degradation products of most of the plastid pigment, the products of Maillard reaction and the content of phenylalanine degradation products in Yunyan87 were the highest, which significantly higher than those in other varieties. K326 had the highest content of cembranoids product, which significantly higher than that of Yunyan87 and Xiangyan3.Xiangyan3 and K326 showed similar contents in most of Maillard reaction products and degradation products of phenylalanine, with no significant differences. Contents of Maillard reaction products and phenylalanine degradation products in YZ206-9 were generally lower than those in other varieties. There are difference both in proportions and contents of chemical constituents and neutral aroma substances among different flue-cured tobacco varieties. |
