The Efficiency of Extracting Biologically Active Substances from the Extracts Based on Mixtures of Medicinal Plants by the Method of Maceration with the Use of Microwave Treatment and Exposure to Ultrasound

This article presents the results of the studies aimed at intensifying the process of extracting biologically active substances (BAS) from medicinal vegetative raw material using the method of maceration with the use of microwave treatment and exposure to ultrasound. The comparative analysis of the obtained data about the yield of BAS has shown that the method of maceration in combination with ultrasound treatment (UT) is the most efficient for extracting the BAS from extracts under the following conditions of extraction: extractant — water, intensity of UT — 100 W/cm2; duration of UT — 10 seconds; treatment frequency — every 10 minutes; and total duration of extraction — 60 minutes. The use of these parameters allows intensifying the process of extraction by increasing the biological value of the extract due to the additional BAS extraction.
