Vegetation changes in the chemical composition of Rosa acicularis

Abstract

In the modern world consumers’ attention is attracted by wholesome, safe and ecologically-friendly food products that can be qualified as "natural". In this regard, wild plants growing in the region seem worth to be involved in processing. Rosaacicularis Lindl is of particular interest as a promising non-traditional medicinal and technical raw material. To assess its quality and use in products recovery, comprehensive information on both the chemical composition of fruits and plant biomass is required. This paper studies the dynamics of biologically active substances transformations in the Rosa acicularis biomass during the growing season. The change in the mechanical composition of the vegetative part of Rosa acicularis in the spring-autumn period is presented. The change in the content of vitamins, organic acids, pectin and tannins, pigments in shoots, leaves, roots and fruits of a plant during the growing season is considered. From May to June - July most biologically active substances are accumulated in the vegetative parts of Rosa acicularis. In fruits the maximum content of biologically active substances falls on August - September. This fact allows recommending not only fruits, but also the vegetative part of the plant for industrial processing.
