Фитохимическое исследование и антирадикальная активность молодых побегов малины обыкновенной

Abstract

Introduction. Young shoots of raspberry vulgaris contain a variety of biologically active substances with pronounced antiradical activity. The aim: Determination of the content of the main groups of biologically active substances and the antiradical activity of leaves and leafless parts of raspberry shoots. Materials and methods of research. Raw material for the study was harvested on the territory of the Ilyinsky district of the Perm Territory in June 2023. Raw material was collected only from well-developed specimens not damaged by pests. Harvested shoots were air-shade dried. Determination of the content of water-soluble polysaccharides was carried out spectrophotometrically using the modified Draywood antron-sulfur method. The determination of the amount of flavonoids in raspberry shoots was carried out by spectrophotometry, by complexation reaction with 2% solution of aluminum chloride. To determine the antiradical activity, a reaction with the stable free radical 2,2-diphenyl-1-picrylhydrazyl was used. Results of research and their discussion. The content of extractive substances extracted by water was found to be higher in raspberry leaves. It was found that the content of water-soluble polysaccharides, tannins and flavonoids is higher in the leaves of ordinary raspberries, compared with the leafless part. Infusion of raspberry ordinary shoots has a pronounced antiradical activity. The antiradical activity of the infusion of raspberry shoots turned out to be higher, compared with the decoction of rosehip fruits which acted as a comparison drug. Conclusion. In the study of biologically active substances, it was found that ordinary raspberry leaves accumulate higher BAS major groups. However, the level of antiradical activity of raspberry infusions of ordinary leaves and leafless parts does not differ significantly.
