“…A ChromSpher 5 Lipids silver-ion chromatography column (250 Â 4.6 mm i.d., Varian, Netherlands) was used for high performance liquid chromatography (HPLC) separation using an isocratic mobile phase with hexane and acetonitrile (99.5:0.5, v/v) at a flow rate of 1 mL/min [16]. The HPLC system consisted of a Yonglin SP930D dual pump (Yonglin, Anayang, Korea) and a Sedex 75 evaporative light-scattering detector (ELSD, Sedex Model 75, Sedere, Alfortville, France).…”
