This article discusses the technology of obtaining dry extract from the leaves of rosemary (Rosmarinus officinalis L.), one of the medicinal plants. The pharmacological significance of biologically active compounds contained in rosemary, including essential oils, phenolic acids, flavonoids and diterpenoids, is analyzed. The process of producing dry extract includes the stages of extraction, filtration, concentration and drying. Scientifically based recommendations are given on the selection of the optimal solvent in the production technology, determination of extraction parameters and ensuring the preservation of biologically active substances.
