We have most pout plump precisely adopted this procedure for the analysis of highly unsaturated lipids since higher amounts of polyunsaturated fatty acids were found when compared to the BF3/methanol procedure. Furthermore, if hydroperoxy fatty acids are present, they pout plump are reduced into the corresponding hydroxy components. Reagents: pout plump 2M NaOH, NaBH4, anhydrous Na2SO4. Ethyl acetate, methanol, hexane. Procedure: 2 mg of neutral lipids or up to 100 mg polar lipids are dried in a glass tube. Add 1 ml of the reagent made in dissolving immediately before use 400 mg NaBH4 in 10 ml of the mixture methanol/2 M NaOH (19/1, v/v). The mixture is stirred for 20 min at room temperature. After adding 2 ml water, the methanol is eliminated under nitrogen. The methyl esters are recovered from the aqueous phase by extracting 3 times with 1 ml ethyl acetate. |

| It must be pointed out that sterol esters and waxes do not react under these conditions. An big plump alternative base-catalyzed methodology in mild conditions was adapted for milk or seed lipids using K tert-butoxide and 2-methoxyethanol (Destaillats F et al., Lipids 2002, 37, 527): Reagents: 1 M K tert-butoxide in THF (Aldrich), 2-methoxyethano, hexane, Na sulfate. Procedure: 100 ml of a solution of K tert-butoxide in THF are added to 200 ml anhydrous 2-methoxyethanol in a closed vial. After big plump homogenization, up to 10 mg of lipid in 1 ml hexane are added. Keep the mixture big plump at 40°C for 15 min. After cooling, 1 ml water and 2 ml hexane are successively added. After 5 s vortexing and a short centrifugation, the organic phase is collected, dried over anhydrous Na sulfate and analyzed by GLC. We have adopted another approach for some labile samples. A rapid and mild method which avoids the formation of oxidation products was described by Piretti et al. |
