Chromatography Summary: | LC/MS analyses were conducted on an Agilent 6550 A QTOF instrument with an Agilent 1290 HPLC with autosampler, operated by Agilent Masshunter software (Santa Clara, CA USA). Separation of the total lipid extracts was achieved by a Thermo (Waltham MA, USA) 100 × 2.1 mm BETASIL 5 μm C18 column at a flow rate of 300 μl/min at room temperature. The mobile phase contained 5 mM ammonium formate (pH 5.0) both in solvent A, acetonitrile:water (60:40, v/v), and solvent B, isopropanol:acetonitrile (90:10, v/v). A gradient elution in the following manner was applied: 68% A, 0–1.5 min; 68–55% A, 1.5–4 min; 55–48% A, 4–5 min; 48–42% A, 5–8 min; 42–34% A, 8–11 min; 34–30% A, 11–14 min; 30–25% A, 14–18 min; 25–3% A, 18–23 min; 3–0% A, 25–30 min; 0% A, 30–35 min; 68% A, 35–40 min. Both the positive-ion and negative-ion ESI MS scans were acquired in the mass range of 200-2000 Da at a rate of 2 scans/min. |
