Summary:The invention discloses a preparation method of sodium cantharidate. The method comprises the following processing steps: performing high temperature carbonization of cantharis, extracting cantharidin, degreasing cantharidin and precipitating, refining cantharidin, synthetizing sodium cantharidate, refining sodium cantharidate, etc. By adopting the preparation method, the extracting time of cantharidin can be greatly shortened, lipidic and peptdic proteins and impurities in crude cantharidin and refined cantharidin can be completely removed, and the yield and purity of cantharidin can be increased. Therefore, sodium cantharidate with higher purity and yield can be obtained, the quality and safety of sodium cantharidate can be further increased and the quality reliability of sodium cantharidate can be increased when used in an injection.
