Thin-layer chromatography (TLC) analysis of propofol-docosahexaenoic acid (propofol-DHA) conjugate synthesis. Synthesis of propofol-DHA was performed as described in the text. The product of the reaction was separated by TLC with a light petroleum (38.3–53.2°C)/ethyl ether (98:2, v/v) solvent system and the products were revealed with iodine vapors. Lane 1, product of the reaction mixture that contained all starting material except propofol; lane 2, product of the complete reaction mixture; lane 3, propofol and DHA standards.
