Deep eutectic solvents are novel media for the extraction of biologically active substances from plant row material. They are often used for ultrasonic extraction. However, due to the high viscosity of the deep eutectic solvents, the question of the sufficiency of ultrasonic exposure for effective diffusion of the target components into the solution remains open. The purpose of this study was to compare the effectiveness of ultrasonic extraction with and without additional mixing. The antioxidant activity of Chamaenerion angustifolium (L.) Scop. extracts obtained by these two methods in the medium of two deep eutectic solvents were compared. It has been shown that additional mixing increases the extraction efficiency concerning antioxidant activity by 20-80%. The obtained data can be used for the development of modern technologies for the isolation of biologically active compounds from plant material using deep eutectic solvents.
