摘要
目的：建立以气相色谱法测定松籽油中γ-亚麻酸含量的方法：方法：色谱柱为5％DEGS柱，检测器温度为220℃，载气为氮气，流速为30ml／min．结果：7亚麻酸检测浓度在1．162-5．81mg／ml范围内线性关系良好（r=0．9995）；平均回收率为97．95％（RSD=0．89％，n=3）。结论：该法灵敏、准确、可靠，适用于松籽油中γ-亚麻酸的含量测定。
OBJECTIVE： To establish the gas chromatography（GC） for the content determination of γ- linolenic acid in songzi oil. METHODS：The separation was performed on 5% DEGS column with detector temperature at 220℃ and flow rate at 30ml/ min, nitrogen gas was used as carrier.RESULTS： The linear range for γ- linoleic acid was 1.162-5.81mg/ ml（r = 0.9 995） .The average recovery was 97.95% （RSD = 0.89%, n = 3） .CONCLUSION：This method was sensitive, accurate and reliable and suitable for the assaying of γ- linoleic acid in songzi oil.
