Abstract
Abstract The extraction method of Friedner and Moberg for determining fecal lipids gave recoveries of medium-chain triglycerides and of octanoic and decanoic acids from stool specimens averaging 103, 97, and 107%, respectively. Fatty acids did not esterify appreciably during extraction. Accordingly, this method is suitable for use in measuring intestinal absorption of triglycerides of medium chain length. The electrical capacitance method of Wolochow et al. is unsuited to the determination of total lipids in a mixture of triglycerides and fatty acids of long and medium chain length because these substances differ widely in capacitance.
