Methods for the determination of the total amount of fat in feces and of the relative proportions of free and combined fatty acids are described. They are based on the principle that fatty acids and fat can be extracted almost quantitatively with petroleum ether from an acidic, alcoholic solution of about 60 per cent ethanol, saturated with NaCl and containing a small amount of amyl alcohol. By these methods the fat in feces can be measured within 35 to 45 minutes with an error not exceeding 2… Expand
Quantitative determination of the saturated and unsaturated higher fatty acids in fecal fat.
A method is described for the quantitative determination of the saturated and unsaturated higher fatty acids in feces. The method is based on the titration of the fatty acids in a purified petroleumExpand
A RAPID, RELIABLE PROCEDURE FOR THE DETERMINATION OF TOTAL FECAL LIPIDS, WITH OBSERVATIONS ON THE COMPOSITION OF THE LIPIDS EXCRETED BY HUMAN SUBJECTS IN NORMAL AND PATHOLOGICAL STATES.
TLDR
The Folch extraction procedure has been adapted to the measurement of total fecal lipids, yielding values in good agreement with those obtained by the more laborious technique of Saxon, confirming the diagnostic superiority of the fat balance technique for the detection of steatorrhea. Expand

1. A new, simple and rapid colorimetric micromethod for determination of total lipids in the petroleum ether extract of feces is proposed. The method, based on the sulfophosphovanillin reaction, wasExpand
Comparison of two direct methods for the determination of fatty acids in infant feces.
TLDR
It is found that the two direct methods for the determination of fatty acids in feces by capillary gas chromatography could be carried out without sample freeze-drying and had certain advantages over Method I, such as speed, safety, and better recovery rates. Expand
Determination of total faecal lipids including medium-chain triglycerides.
Abstract A method is decribed for rapid determination of the total amount of lipids in faeces, including medium-chain triglycerides (MCT). The samples, collected under ethanol for three consecutiveExpand
Evaluation of a spectrophotometric method for determination of total fecal lipid.
TLDR
The slope of near unity indicates that the increased lipid excretion in steatorrhea is almost wholly accounted for by increased triglyceride and fatty acid excretion and that the unsaponifiable fraction remains relatively constant. Expand
A combined thin layer-gas chromatographic method for the analysis of fatty acid-containing stool fractions.
Abstract A method is described which enables the determination of the fatty acid pattern of the major fatty acid-containing faeces fractions and the quantitative estimation of these fractions. AfterExpand
A RAPID METHOD FOR QUANTITATIVE DETERMINATION OF FECAL FAT BASED ON THE PRINCIPLE OF ELECTRICAL CAPACITANCE.
TLDR
Results indicate that the electrical capacitance method provides a sufficiently rapid and quantitative assessment of total fecal fat excretion as a routine clinical procedure for the detection of steatorrhea. Expand
Determination of fecal fats containing both medium and long chain triglycerides and fatty acids.
TLDR
A new method for the measurement of medium-chain triglycerides andMedium-chain fatty acids in feces is described and can be used to measure either fats gravimetrically, or fatty acids titrimetrically. Expand
Determinationof Lipids , IncludingMedium-ChainFattyAcids , in Human Feces
In this method for determining fecal lipids, feces are saponified with ethanolic potassium hydroxide, the ethanol Is evaporated, and the acidified residue extracted with hexane. An aliquot of theExpand
