| titleOfInvention | Preparation method of cardamomin |
| abstract | The invention discloses a preparation method of cardamomin. The method comprises the following steps: taking an Amomum globosum raw material, pulverizing, adding isometric water and biological enzyme, keeping the temperature to carry out enzymolysis for 3-5 hours, adding a saturated lime water solution, carrying out ultrasonic extraction 2-3 times, regulating the pH value of the extracting solution to 5-6, adding into a macroporous resin for adsorption, carrying out gradient elution with an ethanol solution, concentrating and standing the eluate to crystallize, dissolving the crystal in alkaline water, adding a right amount of ethanol, filtering, regulating the pH value to 1-3, standing to crystallize, crystallizing the crystal with an ethanol solution, and drying. The method for preparing cardamomin from Amomum globosum is simple in technique and easy to operate, has the advantage of high product yield, and can easily implement industrial production. |
