HIGH-RESOLUTION GAS-CHROMATOGRAPHIC DETERMINATION OF ALKANOLS IN OILSEXTRACTED FROM OLIVES

Polar columns with stationary phases characterized by high thermal sta bility have attracted a great deal of interest in the study of lipid c ompounds that have, until recently, been studied with nonpolar columns . Such polar columns have also proved useful in the study of the entir e unsaponifiable matter of a lipid and in determining the alkanols of extra-virgin olive oil, husk oil and their relative mixtures. The prop osed procedure permits the study of alkanols without having to isolate them from the other classes of compounds present in the unsaponifiabl e matter by means of thin-layer chromatography.
