Study on the quality standard of the extracts of Periplaneta Americana

Objective: To establish the quality standard of the extracts of Periplaneta Americana. Method: TLC was used to identify the extracts of Periplaneta Americana. UV was used to detect the content of total amino acid and moisture determination method was used to detect the water content. Result: The sample and control medicine showed the same 5 spots in the TLC chromatogram. The linear range of the method of determination of the amino acid content was 0.008 mg﹒mL-1～0.022 mg﹒mL-1(r2=0.9981). The average recovery was 99.3 %( RSD=2.46%). Conclusion: The method is feasible, good reproducibility and can be used in the establishment of the quality control standard of the extract of Periplaneta Americana.
