THE INFLUENCE OF TECHNOLOGICAL PROCESSES ON EXTRACTION OF CHEMICAL COMPOUNDS OF PROPOLIS

Summary The main task of this research was to determine and select non-ethanol solvents for raw propolis material, to create technological procedure for extraction and to determine the active compounds in the extracts. Experiments were performed using pure raw propolis material. The analysis of qualitative and quantitative characteristics of propolis solutions was based on propolis samples collected from different climate regions of Lithuania. The aim of the study was to create technological sequence and to obtain optimal concentration of phenolic compounds in the extracts. The optimal composition and specifications of non-ethanol propolis solution were determined in sequence of experiments.
