抄録

A droplet counter-current chromatography (DCC) method for the separation of contaminants from lipids in fish samples has been developed for food contamination monitoring by GC/MS. Concurrently, the lipid constitution of fish extract has been investigated by HPTLC-densitometry.<br>The main component of crude fish extract was triglyceride (TG) and the other components were diglyceride (DG), cholesterol (Ch), free fatty acid (FFA), monoglyceride (MG), phospholipids (PL), and unknowns.<br>Various industrial chemicals and pesticides were eluted with good separation and reproducibility from DCC according to their partition coefficients between the stationary phase and mobile phase.<br>After removal of almost all TG by acetonitrile n-hexane partition, the remaining lipid was subjected to DCC. Fish extract was fractionated into 8 fractions. These fractions could be concentrated to 0.1-1mL (from 1kg of fish).
