[0048] The preparation method of the American cockroach extract is as follows: the American cockroach uses ethanol as an extraction solvent for alcohol extraction, and the extract is concentrated into an extract to obtain the American cockroach extract.
Embodiment 2
[0050]
[0051]
[0052] The preparation method of described American cockroach extract comprises the steps:
[0053] Step (1), the dried Periplaneta americana body is crushed to a particle size of 60-200um, the pulverized Periplaneta americana body powder is poured into a sample bottle of a rotary evaporator, and then added with a volume concentration of 95% Ethanol, rotating and leaching at 44°C for 3 hours, then filtering, and drying the filter residue in an oven at 49°C;
[0054] The mass ratio of described Periplaneta americana body powder and the volume concentration of 95% ethanol is 0.5:12;
[0055] In step (2), use citric acid and disodium hydrogen phosphate to prepare three kinds of buffer solutions with pHs of 2.0, 7.5, and 8.3, respectively, for subsequent use;
[0056] Step (3), the filter residue after drying in step (1) is added in the buffer solution of pH=2.0 prepared in step (2), the mass volume ratio of the filter residue after drying to the buffer so...
