| 摘 要： | 采用甲酯化、溶剂萃取和GC法定量分析了河南烤烟中的多元酸，如草酸、丙二酸、丁二酸、苹果酸和柠檬酸和高级脂肪酸如肉豆蔻酸、棕榈酸、亚油酸、亚麻酸和硬脂酸。分析步骤为：将含有己二酸（内标）的烟末放入硫酸-甲醇中，在35℃下酯化24h，随后用二氯甲烷萃取3次，用饱和氯化钠溶液洗涤，加入无水硫酸钠干燥，最后进行气相色谱分析。分析结果表明：在所测定河南烤烟中苹果酸、草酸、柠檬酸和亚麻酸的含量均远远高于其它有机酸的含量；下部烟叶高级脂肪酸含量最丰富，中部烟和上部烟的高级脂肪酸含量基本一致。

| Abstract: | The polybasic and higher fatty acids,such as oxalic, malic, citric, palmitic, linoleic and stearic acids in fluecured tobacco were quantitatively analyzed with methyl esterification, solvent extraction and GC. Tobacco powder containing adipic acid （internal standard） was esterified in H2SO4 - CH3OH at 35℃ for 24 hrs, followed by extraction with CH2Cl2 for 3 times, washed with aqueous saturated NaCl solution, dried over anhydrous Na2 SO4 and determined by GC. The results showed that the content of malic, oxalic, citric and linolenic acids in flue - cured tobacco tested was much higher than that of their other organic acids, the content of higher fatty acid in lower stalk position is higher than that of in upper and middle stalk position. |
