title: [Determination of cholesterol and alpha-tocopherol in eggs by capillary gas chromatography].
abstract: A simple and rapid method has been developed for simultaneous determination of cholesterol and alpha-tocopherol in eggs. The method involves alcoholic KOH saponification of the samples, extraction with petroleum ether, and determination by wide-bore capillary gas chromatography. The recoveries of cholesterol and alpha-VE in eggs were 91.0%-93.3% and 82.5%-95.0%, with RSDs of 2.7%-3.1% and 4.9%-6.9% respectively.
