Abstract
It was found by the photocolorimetry method that in acidic media, compositions of natural carboxyl-containing phenols (antioxidants) with monosaccharides (synergists) show an antiradical synergistic effect in reactions with 2,2ʹ-diphenyl-1-picrylhydrazyl, the maximum value of which is typical for binary mixtures of sinapic, gentisic, and ferulic acids with galactose and mannose. It was shown by NMR spectroscopy and difference UV spectroscopy methods that the synergism mechanism consists in the formation of intermolecular hydrogen-bonded phenol-monosaccharide complexes in the ratio of 1:1. A combined model for selecting phenolic-saccharide compositions with high synergistic effect was proposed on the basis of quantum chemical DFT and regression analysis methods.
期刊介绍：
Russian Journal of General Chemistry is a journal that covers many problems that are of general interest to the whole community of chemists. The journal is the successor to Russia’s first chemical journal, Zhurnal Russkogo Khimicheskogo Obshchestva (Journal of the Russian Chemical Society ) founded in 1869 to cover all aspects of chemistry. Now the journal is focused on the interdisciplinary areas of chemistry (organometallics, organometalloids, organoinorganic complexes, mechanochemistry, nanochemistry, etc.), new achievements and long-term results in the field. The journal publishes reviews, current scientific papers, letters to the editor, and discussion papers.
