| titleOfInvention | A method for purifying heavy metals in Curcuma radix medicinal materials based on supercritical extraction |
| abstract | The invention discloses a method for purifying heavy metals in the extraction process of Curcuma curcumae. The extraction raw materials are put into the supercritical extraction kettle and mixed with glass beads thoroughly. The extraction temperature was 50-60°C, the CO fluid pressure was 14-22MPa, the extraction time was 20min, and the amount of 50% ethanol aqueous solution or water as the entrainer was 100ml/kg. The research of the present invention shows that, through the method of supercritical extraction, the heavy metals in the medicinal materials of Curcuma Radix are greatly reduced, and the loss of effective components is lower at the same time. Easy and fast operation, suitable for industrial production. |
