The aim of the work is to experimentally study the effect of pressure, temperature and time of supercritical CO2 (SC-CO2) extraction on the yield of extractives from local raw materials -licorice root. The object of the study was the roots of naked licorice grown in the vicinity of the Bukhara region (border with Turkmenistan). The experiments were carried out in apparatus for SC-CO2-extraction in the laboratories of the Bukhara Engineering-Technological Institute and the Kuban State

The main factors influencing the extraction process of licorice root are taken as follows: T -is the temperature of the extractant (0С), τ is the duration of extraction (min), P is the pressure of the extractant (MPa). The experimental conditions were as follows: pressure 7,5-9,5 MPa, temperature from 310C to 410C, extraction duration 90-150 minutes. The extract yield Yyeld (%) is taken as the sought function. The implementation of the intensified process of licorice root extraction is associated with obtaining calculated equations that allow determining the duration of the extraction process and rational parameters of the extraction mode. For this purpose, we have applied the method of planning multifactor experiments.
