[0060] Further detailed description will be given below in conjunction with the production flow chart of the preparation method of compound emodin baicalein injection.
[0061] The first step: extract pure emodin and baicalein. Firstly, the rhubarb and scutellaria baicalensis are subjected to ultrasonic treatment respectively, so that the yield of emodin and baicalein can be increased by more than 8%-10%.
[0062](1), get the rhubarb medicinal material, add 5 to 8 times the amount of ethanol with a concentration of 60%, soak for 24 to 48 hours, put it in an ultrasonic processor and process it for 20 to 30 minutes, and filter the rhubarb medicinal material after ultrasonic treatment to obtain the filtrate Add 3 to 5 times the ethanol of 60% concentration to the residue, put it in an ultrasonic processor and process it for 20 to 30 minutes, then filter to obtain the filtrate, and then combine the two filtrates; HCl and pH9.9 buffer solution were treated sequentially to obtain c...
