      J. of Chromatogr. A 1218 (19), 2668-2675 (2011). Use of the changes in emission of berberine cation, induced by non-covalent interactions with lipids on silica gel for detection and quantification of lipids using fluorescence densitometry in HPTLC/AMD. Three different HPTLC/AMD gradients were developed for the separation of 1) neutral lipid families and steryl glycosides, 2) different sphingolipids, and 3) sphingosine–sphinganine mixtures. Rationalization of fluorescent molar responses of studied lipids, and differences in response among different lipid families in the light of a previously proposed model of FDIC response, which is based on ion-induced dipole interactions between the fluorophore and the analyte, likewise, application of computational calculations using molecular mechanics as a complementary useful tool to explain high FDIC responses of cholesteryl and steryl-derivatives, and moderate responses of sphingolipids. Proposal of an explanation for the high FDIC response of cholesterol, whose limit of detection is 5 ng.
