Application of spectral fingerprint Identification to fumigation prearetion / 中国基层医药

ABSTRACT

Objective To establish spectrophotometrys for control the quality of fumigation preparation.Methods Two spectrophotometrys were used. 95% ethanol solutions of 5 preparations were detected by ultraviolet spectrophotometry(UV), and chloroform solutions of the preparations were detected by Fourier Transform Infrareds Spectroscopy(FIIR). Results The UV and IR spectra of the solutions were of high similarity respectively,and the absorbance peaks of spectra had the characteristic fingerprint. Conclusion Two spectrophotometrys were all simple,accurate,sensitive,which could be used for the quality control of fumigation preparation.
