| titleOfInvention | Method for extracting reserpine through synergism of enzymolysis and dual-frequency ultrasound |
| abstract | The invention relates to a method for extracting reserpine through synergism of enzymolysis and a dual-frequency ultrasound method. The method comprises the following treatment steps: grinding roots of Rauvolfia vomitoria, allowing the roots to pass through a sieve of 60 meshes, adding an acidic ethanol solution, and regulating the pH value to 3.0-5.0; adding 1-4 percent of cellulase, placing the solution in a dual-frequency ultrasonic extractor, extracting at the temperature of 40-60 DEG C for 90-120 minutes, and sequentially performing inactivation, centrifugation, filtration, neutralization, resin separation and purification, concentration, organic solvent extraction and recrystallization on enzymatic hydrolysate to obtain a reserpine crystal. The Rauvolfia vomitoria serves as the raw material, dual effects of enzymolysis and dual-frequency ultrasonic extraction are fully utilized, the reserpine in the Rauvolfia vomitoria is dissolved out to the greatest degree, and the method has the advantages of simple process, short extraction time, small amount of organic solvents and low toxicity and is suitable for large-scale production. |
