PHYTOCHEMICAL ANALYSIS AND ANTIOXIDANT PROPERTIES OF PLANT EXTRACTS OF THE ROSACEAE FAMILY

Oxidative stress is considered as an important pathogenetic link in the development of more than 200 diseases. In this regard, the search for local medicinal plant raw materials with a high content of phenolic compounds with antioxidant activity to inhibit oxidative processes becomes the current task. The article presents data on the content of biologically active compounds and total antioxidant capacity of extracts of Crataegus dahurica, Sanguisorba officinalis, Rosa acicularis. It was shown that among the plants the high content of flavonoids and total phenolic compounds was found in the extracts of R. acicularis, while phenylpropanoids were predominant in the leaves of S. officinalis. High antioxidant capacity was found in leaf extracts of R. acicularis, which correlates with the increased content of phenolic compounds in this plant.
