摘　　要：为了解不同部位不同等级烤烟和不同价类卷烟中的苹果酸、柠檬酸和草酸含量的差异,采用气相色谱法测定了2003年云南生产的40个烤烟烟叶样品、52个卷烟样品以及梗丝、再造烟叶、膨胀烟丝样品中的苹果酸、柠檬酸与草酸的含量。结果表明:①上部烟叶中的草酸含量较中、下部高,中、下部草酸的含量基本接近,苹果酸、柠檬酸含量及苹果酸、柠檬酸、草酸含量之和随部位的下降而增加;②不同等级烟叶中的草酸、苹果酸和柠檬酸的含量差异较小,低等级烟叶中的柠檬酸含量相对较高;③高价类卷烟样品中的苹果酸、柠檬酸、草酸含量比低价类卷烟的低,其苹果酸与柠檬酸的比值在7.0左右;④烤烟型卷烟样品的草酸/柠檬酸之比>0.80,柠檬酸占苹果酸、柠檬酸和草酸含量之和(三酸和)的百分比<20%,而混合型卷烟样品的草酸/柠檬酸之比、柠檬酸占三酸和的百分比则相反。In order to investigate malic, citric and oxalic acid contents in different grade flue-cured tobacco leaves and cigarettes of different price categories, 40 flue-cured tobacco leaf samples produced in Yunnan Province in 2003, 52 cigarette samples, cut stem, reconstituted tobacco and expanded cut tobacco were analyzed with GC. The results showed that： 1） oxalic acid content in middle leaf was similar to that in lower leaf but lower than that in upper leaf, the contents of malic and citric acids and the total of the 3 acids in leaves increased with the descent of stalk positions; 2） the content difference of oxalic, malic and citric acids in different grades was not significant, though the content of citric acid in lower grade leaves was slightly higher; 3） malic, citric and oxalic acids contents in premium cigarettes were lower than those in low-price cigarettes, the ratio of malic acid to citric acid was about 7.0; 4） in Virginia type cigarettes, the ratio of oxalic acid to citric acid was over 0.80 and citric acid accounted for less than 20% of the sum of the 3 acids, however these relations in blended type cigarette samples were on the contrary.
