2.2.5. HPLC analysis
An HPLC chromatograph (Agilent 1100 Series) equipped with a micro vacuum degasser, a binary gradient system, a thermostated column compartment and a variable wavelength detector was employed. A Zorbax Eclipse XDB-C18 column (4.6 × 150 mm with 5 μm particle size) was used for separation. The column temperature was held constant at 40 °C. The injection volume of 20 μL and flow rate of 1 mL/min were applied in all experiments. The mobile phase was methanol (reservoir A) and 2-propanol/n-hexane (5:4 v/v; reservoir B). A linear gradient from 100% A to 40% A + 60% B in 15 min was employed. Components were detected at 205 nm. The calibration curves were prepared by using the standard mixture of FAME and the standard glycerides.
