| titleOfInvention | Countercurrent ultrasonic preparation method of propolis extract |
| abstract | The invention discloses a countercurrent ultrasonic preparation method of a propolis extract, belonging to the field of development and utilization of propolis active ingredients. Comprises the technical processes of crushing raw materials, adding a solvent for blending, ultrasonic extracting, solid-liquid separating, drying, recovering the solvent and the like. The invention has the advantages that: active ingredients in the propolis are extracted by utilizing countercurrent energy-gathering type ultrasonic circulation, and meanwhile, helium is used for protecting easily-oxidized ingredients from being lost in ultrasonic extraction, compared with the existing method, the extraction time is shortened by 48-99.8%, the extraction rate of soluble substances is improved by 37.2-172%, and the content of flavone in the extract is improved by 46-279%. |
