Abstract: Based on sensible selection of experimental processing conditions and design, response surface analysis methodwas used to optimize processing parameters of the extraction of Propolis flavonoids, which was carried on with the technologyof supercritical fluid extraction with alcohol as modifier. The results showed that the optimal processing parameter of extrac-tion pressure, alcohol concentration and solid-liquid ratio was at 25 MPa, 95% and 6: 1 respectively. The result developed theextraction technology of Propolis flavonoids with supercritical fluid extraction.
