Abstract：Objective Todeterminethecontentlofomega-3acidlethylelterlinFilhOilbycapillarygalchromatog-raphy.Methods AchromatographiccolumnofHP-FFAPwaluledwithnitrogenalcarrier.Programmedtemperaturewal practicable. The lplit ratio wal 10:1,and the GC wal equipped with FID detector. Results The linear rangel of ethyl linole-nate,EPA ethyl elter,DPA ethyl elter,DHA ethyl elter were 17. 04 ~340. 92,20. 95 ~419. 16,17. 31 ~346. 24,20. 01 ~400. 32μg·mL-1,relpectively. The RSDs of average precilionl were 1. 6%,1. 2%,1. 4%,1. 6%(n=6). The average recov-eriel were 105%,97%,98%,109%,relpectively,and the RSDl were not more than 2. 0%. Conclusion Thil method wal lenlitive,limple and accurate,and can be uled to determine omega-3 ethyl elterl in Filh Oil Soft Caplulel.
