The invention relates to the field of
medicine, in particular to a preparation process of an Eddy injection preparation. The preparation process of the Eddy injection preparation comprises the following steps: taking Chinese
blister beetle,
ginseng,
astragalus membranaceus and acanthopanax as raw materials, performing warm dipping on the
ginseng and performing
alcohol extraction, jointly decoctingthe
ginseng residues, the
astragalus membranaceus and the acanthopanax and performing aqueous extraction, combining extraction liquid, performing
alcohol and water
precipitation alternately for manytimes and performing
refrigeration treatment so as to completely precipitate and remove the impurities, greatly reduce the impurities in the
medicine liquid and reduce the occurrence rate of adverse reaction, adjusting the pH, performing
ultrafiltration and performing
refrigeration for later use; performing warm dipping on the Chinese
blister beetle and performing aqueous extraction, performing treatment by a
lime surface method, performing
alcohol precipitation for twice, refrigerating, filtering, performing water
precipitation for twice, adjusting the pH, refrigerating and performing
ultrafiltration; and mixing the Chinese
blister beetle extracting liquid, the extracting liquid of the ginseng, the
astragalus membranaceus and the acanthopanax, adding auxiliary materials and adjusting thepH. The preparation process of the Eddy injection preparation has the advantages of high extraction efficiency, high purity and low occurrence rate of adverse reaction.
