[0016] The following is the specific implementation of the present invention given by the inventor, combined with a further detailed description of the preferred embodiments.
[0017] 1. Supercritical extraction of Cnidium monnieri medicinal materials
[0018] Take 1,000 g of the Cnidium acuminata fruit powder, smash, pass through a 20-mesh sieve, weigh the powder, and place it in an extraction kettle. After the refrigeration device, the extraction kettle and the separation kettle heating device work normally, turn on the compression pump to pressurize to 20.0MP, the temperature is 40℃, and adjust the carbon dioxide (CO 2 ) Circulating extraction with a flow rate of 40kg / h, the desorption pressure and desorption temperature of the separation tank are 6MP and 50°C, respectively, after 4h of extraction, the extract is fractionated to obtain the Cnidium monnieri extract.
[0019] 2. Separation and purification of the effective components in the extract of Cnidium monnieri
