Determination of the total content of antioxidants in varieties of aromatic plants, introduced in the Mountains of Dagestan

The paper presents the results of a comparative study of the total antioxidant activity (CCA) of five varieties of Hyssopus officinalis L: Accord, Amethyst, Blue, Country Doctor, Otradny; three varieties of Dracocephalum moldavica L.: Albion, Gorynych, Lemon Aroma; three varieties of Satureja hortensis L.: Fragrant, Gnome, Pepper flavor. In carrying out the work, a unique scientific installation of the Gorbadov Scientific Center of the Scientific Center "System of experimental bases located along a high-altitude gradient" of 1,100 m above sea level (Tsudakhar experimental base) was used. The total content of antioxidants in alcohol extracts obtained from the aerial part of the plant was determined using the amperometric method on the Yauza 01 - AA device, based on measuring the electric current in an electrochemical cell that occurs when a certain potential is applied to the electrode. It was found that the highest content of antioxidants in the aerial parts of the varieties Amethyst, Aromatic, Gnome, which determines their biological value as a raw material for use in medicinal compositions. It was shown that there is a positive correlation between the accumulation of essential oils and antioxidant activity for the studied varieties. It has been established that antioxidant activity depends on the species specificity of plants, on their varietal characteristics. A correlation analysis conducted between essential oils and antioxidants showed the presence of a positive correlation between them.
