Other Notes eluate post-treatment: Approximately 100 μL of the lipid fraction transferred to a Pyrex tube, dried under nitrogen, and subsequently transesterified with 1 mL of a sodium methoxide/methanol mixture (0.5 %, w/v) at 100 °C for 15 min; after cooling, 1 mL of boron trifluoride-methanol added, and the solution heated at 100 °C for 15 min; after cooling, 1.0 mL of n-hexane, 1.0 mL of a sodium chloride saturated solution in distilled water, and anhydrous sodium sulfate were added to the mixture, agitated manually for 1 min, and centrifuged at 4000 rpm for 2 min; approximately 1.0 mL of the upper n-hexane layer transferred to a 2.0 mL autosampler vial and stored at 4 °C until analysis
