The article discusses the hyssop plant «Medicinal», growing in Michurinsk on the basis of the NFC «Michurina». Based on its chemical composition, the areas of its possible application are presented. Based on the studies, conclusions are drawn and the results of the extraction kinetics of this plant are shown. Samples of the feedstock were cut in the form of a complex straw (herringbone) 20 ± 5 mm long and dried by convection to a residual moisture content of 8 %. A comparative analysis of two extraction methods and hydromodules 1:50 and 1: 100 made it possible to establish the features of each mode. Based on the results obtained, the influence of vacuum on the intensification of the extraction process was identified and a rational hydromodule for water extraction of hyssop “Medicinal” was determined. The most suitable parameters for the extraction of hyssop have been established, allowing to reduce the process time by 15 minutes, minimize energy consumption by 20 % and increase the concentration of dry water-soluble substances by 25 %. In addition, to increase the shelf life, it is proposed to use water-alcohol extraction with an ethyl alcohol content of 10%. Based on the results of the research, conclusions are drawn.
