| titleOfInvention | A kind of ethanol warm soaking method prepares the method of helicic acid |
| abstract | The present invention provides a method for preparing salicylic acid by an ethanol warm soaking method, comprising the following steps: (1) performing warm soaking and extraction on the medicinal material of Amla amla with a particle size of 5-20 meshes at a temperature of 40-60°C, and the warm soaking and extraction The solvent used is 50-80% ethanol to obtain an extract; the extract is concentrated, then dispersed with water, and subjected to solid-liquid separation, centrifugation or filtration to obtain a supernatant; (2) the liquid separated in step (1) Adsorbed by macroporous adsorption resin HPD-400, the adsorption flow rate is 0.5-2ml/min, eluted with water, the elution flow rate is 0.2-3ml/min, and the eluate is dried under reduced pressure. The method is simple, high in content and transfer rate, and the verification results of the scale-up process also show that the established preparation process is stable and feasible, and is suitable for industrial production needs. |
