title: Technological approach of 1-O-alkyl-sn-glycerols separation from Berryteuthis magister squid liver oil.
abstract: Biological active compounds, 1-O-alkyl-sn-glycerols (AG), were isolated from liver oil of the squid Berryteuthis magister. The main components of the initial lipids were 1-O-alkyl-2,3-diacyl-sn-glycerols (38.50 %) and triacylglycerols (24.26 %). The first step of separation was the alkaline hydrolysis of oil to form a lipid mixture consisting of AG, free fatty acids and cholesterol. AG were separated by double recrystallization from acetone at -20 °C and 1 °C. A simple procedure is proposed for obtaining AG with a purity of 99.22 %, the main component of which is chimyl alcohol (94.39 %). Purity and structure of the obtained products were confirmed by GC and GC-MS technique. Isolated AG may be used in nutrition and cosmetics.
