摘要
目的 用气相色谱法测定红花籽油中亚油酸的含量。方法 色谱柱为涂布 1 0 %的丁二酸二乙二醇聚酯 (DEGS)固定液的石英玻璃柱 (3mm× 3m) ,柱温 1 80℃ ,检测器温度 2 30℃。结果 亚油酸在 1 5 .0 6～ 90 .44mg·ml- 1 浓度范围内 ,线性关系良好 (A =1 2 6863 .8+1 4 570 0 .4C ,r =0 .9995) ,回收率为 98.75 % ,RSD =1 .2 1 %。
OBJECTIVE To determine the linoleic acid contents in the oil from Carthamus tinctorius L.seeds. METHODS A GC analysis method was establised.The column was 3 mm×3 m quartz glass tube packed with 10% DEGS. The column and the FID temperature were 180℃and 230℃, respectively. RESULTS The standard curve was linear within the range of 15.06-90.44 mg·ml -1 (A=126863.8 +145700.4 C,r= 0.9995). The recovery of linoleic acid was 98.75%,and RSD was 1.21%. CONCLUSION It can be used for quality control in the oil from Carthamus tinctorius L. seeds.
