AbstractThis article describes a possible combination of two promising fields of analytical chemistry—the preparation of sol‐gel matrices with varying additives and their application in capillary electrochromatography. The inner surfaces of capillaries were coated with the sol‐gel solution containing either pure synthetic chemical additive—alliin or capsaicin—or an extract of their natural sources—garlic and chilli pepper, respectively. The modified capillaries were tested for interaction with two neurotransmitters, oligopeptides and nucleotides under conditions of open‐tubular capillary electrochromatography. Because both of the natural extracts also contain vitamin C and saccharose, the capillaries with sol‐gel modifiers containing each of these substances were also tested. The obtained results from the perspective of changes in the electrochromatograms and the effective mobilities of analytes are discussed with respect to mild conditions both in the preparation process of the sol‐gel matrix and during the separations.
