This paper presents the results a study of the qualitative and quantitative composition of components of the polyphenolic complex in grapes of the introduced Rkatsiteli and Moldova varieties, which grow in the arid conditions in the northwestern part of the lowland zone of Dagestan as a model sample that is characteristic of the southern regions of Russia. The content of the complex of phenolic compounds, vitamins, and reductones in grapes and the products of their processing is determined. The paper assesses the antioxidant activity of the individual structural elements of a grape bunch: pulp, skin, seeds and combs. The obtained data were used in the development of technological modes for processing of the studied varieties to prepare wines and wine materials.
