本文建立了气相色谱法快速测定元宝枫油中神经酸含量的检测方法。样品用硫酸甲醇法进行脂肪酸甲酯制备，用正已烷进行提取，气相色谱法测定，外标法定量。方法的平均回收率在91%～97%，精密度RSD＜5%。此方法适用于快速测定元宝枫油中神经酸的含量。
本文建立瞭氣相色譜法快速測定元寶楓油中神經痠含量的檢測方法。樣品用硫痠甲醇法進行脂肪痠甲酯製備，用正已烷進行提取，氣相色譜法測定，外標法定量。方法的平均迴收率在91%～97%，精密度RSD＜5%。此方法適用于快速測定元寶楓油中神經痠的含量。

Detection method of nervonic acid in acer truncatum buge oil by gas chromatography was established. Samples preparation of methyl esters by fatty acids sulfate acid-methanol, which were extracted with hexane. Method was analyzed by GC and quantified using external calibration curves. Extraction recoveries were 91%-97%, RSD was less than 5%. Method was suitable for the rapid determination of nervonic acid in acer truncatum buge oil.
