ANALYSIS OF PROMISING MEDICINAL PLANTS FOR PREPARING ANTIOXIDANT THERAPEUTIC HERBAL SPECIES
Medicinal plants are a source of various biologically active compounds. Polyphenols, vitamin C as well as macro- and microelements perform an important function in protecting the human body from reactive oxygen intermediates during the development of oxidative stress. Antioxidant activity, micro- and macronutrient composition of leaves were studied: Chamaenerion angustifolium, Ribes nigrum, Fragaria vesca, Rubus caesius and Wisteria sinensis. Antioxidant activity of the herbal species was 116,5 mg/g. The following elements: Mg, P, K, Ca, Cr, Mn, Fe, Cu, Se, Zn, Si, Al, Mo, Na, Sr were determined in the leaves of the medicinal plants studied by the methods of atomic-absorption spectroscopy with electrothermal atomization of the substance (spectrometer iCE 3500) and atomic emission spectroscopy (spectrograph DFS-8). The content of the main groups of biologically active compounds in herbal species is: ascorbic acid - 1,60 %, flavonoids - 10,68 %, hydroxy-cinnamic acids - 2,39 %, free organic acids - 12,59 %, tannins - 12,47%.
