✦ Synopsis

A procedure for preparing polyamide thin layers and chromatographic solvents necessary for a distinct separation of gallic acid and its alkyl esters has been described. A clean-up procedure necessary for the separation and identification of these compounds from fatty foods was investigated.

All the procedures were very simple, convenient and feasible for the analysis of these compounds and will also be applicable to the separation and identification of other gallic acid esters in fatty foods.
