Abstract
Mono- and diglycerides play an important role in the metabolism of plants and animals. They are usually constitutive elements of complex mixtures and are not always as main components, which considerably hinder the identification of these analytes. This work communicates about a synthesis of a wide range of esters of glycerol and aliphatic C(6)-C(20) acids and presents gas chromatographic characteristics of 32 compounds in the form of the most reproducible parameters-linear-programmed retention indices on high-performance capillary columns with non-polar stationary phases. The article also presents mass spectra for a series of those glycerides which were not characterized earlier by these parameters.
