摘要
目的:建立同时测定火麻仁中的α-亚麻酸、亚油酸和油酸含量的HPLC方法。方法:色谱柱为Kromasil 100-5 C18(4.6 mm×250 mm,5μm),以乙腈-0.1%磷酸(80∶20)为流动相,流速1 mL.min-1,柱温30℃,检测波长203 nm。结果:α-亚麻酸在34.625~554 mg.L-1(r=0.999 9),亚油酸在56.375~902 mg.L-1(r=1),油酸在17.125~274 mg.L-1(r=0.999 9)呈良好的线性关系;平均回收率α-亚麻酸为96.38%,RSD 0.93%(n=6);亚油酸为97.79%,RSD 0.92%(n=6);油酸为97.06%,RSD 1.51%(n=6)。结论:本法简便准确,专属性强,重复性好,可作为火麻仁的质量控制的参考。
Objective:To establish a HPLC method for the determination of α-linoleic acid,linoleic acid and oleic acid in Hemp Seed.Method: The Kromasil 100-5 C18(4.6 mm×250 mm,5 μm) column was used with a mobile phase of acetonitrile-0.1% phosphoric acid(80∶20),the flow rate was 1 mL·min-1,the column temperature was at 30 ℃,the detection wavelength was at 203 nm.Result: The linear ranges of α-linoleic acid,linoleic acid and oleic acid were 34.625-554 mg·L-1(r=0.999 9),56.375-902 mg·L-1(r=1) and 17.125-274 mg·L-1(r=0.999 9) respectively.The average recoveries were 96.38% with RSD 0.93% for α-linoleic acid,97.79% with RSD 0.92% for linoleic acid,97.06% with RSD 1.51% for oleic acid.Conclusion: The method can be used to control the quality of α-linoleic acid,linoleic acid and oleic acid in Hemp Seed,which is simple,accurate,convenient,specific and repeatable.
