Abstract
The free and esterified (“bound”) hydroxy acids from butterfat were isolated by column- and thin-layer chromatography on silica. The 4- and 5-hydroxy acids forming the γ- and δ-lactones were separated from the other hydroxy acids by TLC on silica. The concentrations of a number of free and bound lactones in butterfat were determined by means of a radio-gas chromatograph using the isotope dilution method. In addition the total concentration of the free and bound hydroxy acids which cannot be lactonized, was determined.
