Embodiment 1
[0044] A pharmaceutical composition for treating psoriasis, comprising Pokeweed extract, component A and component B;
[0045] The preparation method of the pokeweed extract is as follows: after the pokeweed is harvested, the leaves are removed, dried and crushed in an oven at 60°C, and then put into the extraction kettle, and the refrigeration device, the extraction kettle and the heating device are normal After work, turn on the compression pump to pressurize to the required pressure, adjust the CO 2 flow rate, for supercritical CO 2 Extraction, fixed separation pressure 4MPa during extraction, extraction pressure 30MPa, extraction temperature 50°C, CO 2 The flow rate is 18L / h, and the extraction time is 4.5h. After extraction, the liquid in the separation tank is collected, water and dichloromethane are added to extract and separated, and the dichloromethane phase is concentrated under reduced pressure and dried to obtain the pokeweed extract ;
