| titleOfInvention | Method for separating phorbol alcohol by utilizing ultrasonic-assisted alcoholysis-extraction coupling technology |
| abstract | The invention relates to the technical field of natural medicine extraction, and particularly discloses a method for separating phorbol by using an ultrasonic-assisted alcoholysis-extraction coupling technology. The method comprises the following steps: s1, uniformly mixing 1 part of croton oil and 5-25 parts of saturated alkaline alcohol solution according to the volume ratio of the material liquid, carrying out alcoholysis-extraction under the action of ultrasonic waves, and standing and separating to obtain an alkaline supernatant containing phorbol and a croton oil lower phase liquid; s2, adjusting the pH of the obtained alkaline supernatant to neutral with acidic alcohol solution, and removing the precipitate to obtain neutral alcohol solution containing phorbol. The invention utilizes an ultrasonic-assisted alcoholysis-extraction coupling method to extract phorbol from croton oil, the alcoholysis and the extraction are synchronously carried out, the alcoholysis-extraction coupling is favorable for improving the alcoholysis efficiency, and the alcoholysis-extraction is quicker and more efficient under the assistance of ultrasonic waves, thereby saving the time and improving the purity of phorbol. Has the advantages of few operation steps, short time consumption, small solvent consumption and easy popularization and application. |
