FIELD: CHEMISTRY.
SUBSTANCE: crushed plant raw material with addition of ethanol modifier is extracted in two stages. At the first stage, supercritical carbon dioxide is used, which results in carbon dioxide extract further dissolved in ethanol by bubbling the extraction agent at atmospheric pressure. At the second stage, solvent cake is extracted with ethanol solution, which results in ethanolic extract.
EFFECT: invention increases grade of extraction of biologically active substances.
