Quality Control Study Based On Chemical Composition Of Equus Asinus Hide

Objective: By comparing the chemical composition of animal skin foundcharacteristic, thereby identifying the authenticity of animal skin,effectively prevent the occurrence of counterfeit medicine cases; anotherchemical comparing different varieties and different years of corruptionaround the composition of animal skin changes, clear changes before and afterthe corruption, to identify whether corruption on the basis of donkey skin,and to find better quality leather donkey breeds and the best growth years,guiding the actual production, provide a theoretical basis for the regulationof animal skin and the quality of gelatin.Methods: Several similar comparison with animal skin glue rate, UVabsorption spectroscopy and HPLC profiles were measured before and afterdifferent varieties and different life animal skin glue rate of corruption,establishing different varieties and different years Equus Asinus Hidecorruption UV absorption spectra before and after and HPLC fingerprint.Results: Five kinds of animal skin glue in the rate of UV absorptionspectra and HPLC profiles of these three areas have shown a difference, youcan distinguish between these three aspects to the other four kinds of animalskin. Similarly, after five growth-years of the five species of Equus Asinus Hide and corruption in a plastic sample rate, UV absorption spectroscopy andHPLC profiles of the three aspects also there is a big difference, you candetermine the extent of corruption in Equus Asinus Hide.Conclusion: Rate through the glue, UV absorption spectroscopy and HPLCchromatograms of these indicators to determine whether adulterated EquusAsinus Hide, and whether the extent of corruption and corruption in order todetermine whether it can be used as medicine brewed gelatin, gelatinindirectly controlled efficacy and quality.
