摘要
为了掌握西南烟草种植区烤烟中石油醚提取物含量的差异,测定了该烟区384个陈化烤烟样品中石油醚提取物的含量,并对检测结果进行了统计分析。结果表明:①贵州烤烟样品中石油醚提取物含量最高,四川次之,云南最低;②上部烟叶中的石油醚提取物含量较高;③2009年度烤烟中石油醚提取物含量要高于2008和2007年度烤烟样品;④贵州烤烟C3F中的石油醚提取物含量要明显高于相同等级的云南和四川烤烟。
The petroleum ether extract contents of 384 flue-cured tobacco samples in southwest tobacco-growing areas were determined , and variation of petroleum ether extract contents were analyzed. The results showed that： （i） Average contents of petroleum ether extract in flue- cured tobacco of Guizhou province were the highest in southwest tobacco-growing areas, Sichuan was the second,and Yunnan was the least. （ii） Average contents of petroleum ether extract in upper leaf was higher than those of other stalk positions. （iii） Average contents of petrole- um ether extract in 2009 was higher than those of 2007and 2008. （iv） Average contents of petroleum ether extract in C3F flue-cured tobacco of Guizhou province were higher than those of Yunnan and Siehuan province.
