摘　　要：用气相色谱法测定9个不同产地椒目中5脂肪酸成分和含量。实验采用闪式提取法得到总脂肪酸后,经2 mol/L KOH皂化,PEG柱分析后,用氢火焰检测器检测。结果表明,9个不同产地的椒目中5种脂肪酸含量和分布存在显著性差异。其中5种脂肪酸总含量最高为四川产椒目96.25%,α-亚麻酸含量最高为重庆产椒目40.19%,油酸含量最高为四川产椒目36.41%,亚油酸含量最高为河北产椒目32.72%。To study the fatty acid constituents and determine their contents of zanthoxylum seed from different places by GC.Flash extraction was used to extract the total fatty acid.The analysis was performed on PEG column after the total fatty acid was snification by 2 mol/L KOH. The results showed that , from 9 different places of zanthoxylum seed in 5 kinds of fatty acid content and distribution in the presence of significant difference.Among the 5 kinds of fatty acids in total was the highest for Sichuan produce JiaoMu 96.25%,α-linolenic acid content was the highest for Chongqing produce JiaoMu 40.19 %, oleic acid content was highest for Sichuan produce JiaoMu 36.41%, linoleic acid content was highest for Hebei produce JiaoMu 32.71%.
