SEARCHING AND STUDYING OF THE STRUCTURE OF HYDROCQUINONE GLYCOSIDES IN THE EXTRACT OF LINGONBERRY LEAVES VACCINIA VITIS-IDEA L. BY GAS CHROMATO-MASS SPECTROMETRY METHOD

Lingonberry is an evergreen representative of the heather family. Among the simple phenolic glycosides in the photosynthetic organs of representatives of the heather family, arbutin- hydroquinone--D-glucopyranoside dominates, which can be used as an antiseptic for the treatment of urinary tract infections. Its bactericidal activity is probably due to hydroquinone released from arbutin under the action of β-glucosidase. The aim of the work is to search for and study the structure of hydroquinone glycosides in silylated cranberry leaf extract using gas chromatography mass spectrometry. Three compounds were found – arbutin, acetylarbutin and unidentified glycoside. The data obtained can be useful both for optimizing the methods of standardization of lingonberry leaves as medicinal raw materials, and for understanding the processes of biosynthesis in the plant, as well as for developing new biologically active compounds based on the knowledge gained.
