Icosapentaenoic acid (IPA) and docosahexaenoic acid (DHA) in five purified fish oils were determined by gas chromatography (GC).<BR>These food components have recently drawn public attention, so the results were expressed as mg/g.<BR>A DB-WAX capillary column was used for the GC, due to its greater separation efficiency. The esterification was compared using both the boron trifluoride-methanol (BF3-methanol) method and the potassium hydroxide-methanol (KOH-methanol) method. The IPA content determined by the KOH-methanol method was found to be approximately 15% higher than by the BF3-methanol method. The DHA content by the KOH-methanol method was also higher by 5%. Determinations of IPA and DHA by both methods showed an intra-laboratory variation of less than 2.5%.<BR>These experimental data showed that IPA and DHA in refined fish oils can be accurately determined by capillary column GC and the esterification using KOH-methanol method.
