Infrared Spectral Analysis of Yinhuang Medicinal Broth and Its Membrane Fraction / 中国中医药信息杂志

Objective To discuss difference of Yinhuang medicinal broth and its membrane fraction from macroscopic quality,provide reasonable experimental basis for membrane system.Methods Method of infrared spectral analysis was used to compare absorption peak position,peak intensity,correlation coefficient of spectrogram of Yinhuang medicinal broth and membrane fraction,judge separation efficiency by overall analysis the spectrogram.Results There was a lots of same peak position at Yinhuang medicinal broth and final membrane fraction.Their coefficient correlation was 0.832 7.Conclusion After impurity removal and concentration by two kind of membrane,Yinhuang medicinal broth lose a little ingredient, so the selection of membrane system is reasonable.
