Abstract:
Raw materials of plant origin, as well as their extracts, contain natural antioxidants whose presence in small amounts delays or slows the oxidative changes of substrates that easily oxidize. The need for plants and their extracts in the form of pharmaceutical and dietary products is increasing from year to year, so they are increasingly the subject of attention of a large number of researchers. Recently, the research on antioxidant and biological effects of medicinal herbs has been particularly intensifying, due to the tendency of replacing synthetic biologically active compounds with natural compounds. In this paper, the research was conducted on the antioxidative effect of sage extract, depending on the concentration of ethanol as a solvent in the process of maceration with occasional mixing. The content of total phenolic and flavonoids in the obtained sage extract was determined spectrophotometrically. The radical scavening capacity was determined by the DPPH method, where the extract concentration needed to neutralize 50% of the initial concentration of the DPPH radical was also determined.
