Аннотация: The antiradical properties of essential oil and water-alcohol extracts of oregano (Origanum vulgare L.), which grows in the Krasnoyarsk territory, were studied in model reactions with a free stable 2,2-diphenyl-1-picrylhydrazyl radical. Essential oil is obtained by exhaustive hydro-distillation. Separate fractions of oil: First 10 Показать полностьюminutes from the start of the distillation, the second-after 20 min, the third after 40 min, and the fourth in 80 minutes, a fifth fraction was collected after the end of hydroponically. The results of the DPPH test showed that all the studied samples of essential oil exhibit anti-radical activity (ARA), the values of which increase from 30.4% (the first fraction) to 51.0% (the fifth). The ARA of O. vulgare whole oil was 36.1%. The ARA values of O. vulgare water-alcohol extracts vary from 56.6 to 100% depending on the alcohol concentration and the volume of the added extract. The highest anti-radical activity is 70% extract, and the lowest-96%. According to the ARA value, the studied extracts and essential oil are O. vulgare, which grows in the Siberian region, can be arranged in the following order: 70% water-alcohol extract >40% extract >20% extract >water extract >96% alcohol extract >essential oil. © 2021 Altai State University.
