| titleOfInvention | Method for preparing high-purity water-soluble oleuropein by reduced pressure ultrasonic-assisted extraction |
| abstract | The invention discloses a method for preparing high-purity water-soluble oleuropein by reduced pressure ultrasonic-assisted extraction, which belongs to the technical field of natural medicine extraction and preparation and comprises the following steps: the method comprises the steps of pretreatment of medicinal materials, ultrasonic extraction under reduced pressure, extraction-back extraction, decolorization, crystallization-recrystallization. The invention provides a novel process for preparing oleuropein with high purity and good water solubility by utilizing vacuum degree generated by decompression and cavitation effect and stirring effect generated by ultrasonic waves and adding a certain amount of extracting solution according to the characteristics of low melting point, easy decomposition and the like of the oleuropein through a simple separation and purification process. The product prepared by the process has the content of more than 95 percent, has the advantages of high product yield, simple process, mild separation and purification conditions, low toxicity, low production cost and the like, and is suitable for industrial production. |
