Abstrakt
Fatty acids and hydroxy fatty acids in the intestine are of interest because of their cathartic properties. We describe a method for extraction of lipids from freeze dried homogenized stools and identification of the hydroxy stearic acid in the fecal lipids pattern by GC-MS. Recovery of 90-95 % shows the efficacy of extraction . Quantitative data of fecal hydroxy stearic acid excretion in some normal and chronic diarrhea affected children are reported.
