| titleOfInvention | Method for efficiently preparing kaempferia galanga extract |
| abstract | The invention discloses a method for efficiently preparing a kaempferia galangal extract. The method comprises the following steps: pulverizing radix Inulae into 50-80 mesh powder, adding supercritical CO 2 An extraction kettle is set at 50-60 ℃ and 15-30 MPa, and liquid CO is introduced 2 Introducing methanol as entrainer with the flow of 2-3 ml/min/g, extracting for 60-100 min, and resolving to obtain extract; dissolving the above extract with ethanol solution, adding active carbon, refluxing for decolorizing, concentrating decolorized solution, extracting with ethyl acetate, concentrating the extractive solution, crystallizing, dissolving crystal with ethanol, separating by high speed countercurrent chromatography, collecting fraction according to chromatography, concentrating under reduced pressure, and drying. The method for preparing the kaempferia galangal extract has the advantages of simple preparation process, small pollution and easy realization of industrial production. |
