Extraction technology for ammonium oxalate of bombyx batryticatus

The invention discloses extraction technology for ammonium oxalate of bombyx batryticatus, which comprises the steps of: taking the bombyx batryticatus as a raw material, adding an organic solvent to soak to remove fat soluble substances, taking remaining residue, adding water into the remaining residue, adjusting the mass/volume ratio of the remaining residue to the water in a feed liquid to 1:10-30 and the temperature to between 60 and 100 DEG C, performing heat extraction for 30 to 90min, and then removing macromolecular substances such as polysaccharides and protein through ethanol precipitation to obtain the ammonium oxalate of bombyx batryticatus. The extraction technology has the advantages of simple steps, high extraction rate of the ammonium oxalate of bombyx batryticatus, and convenient industrialized implementation, also improves the purity of the ammonium oxalate of bombyx batryticatus, and develops the application of the bombyx batryticatus in the field of medicaments.
