银黄水煎液及其膜分离产物的红外光谱分析

Infrared Spectral Analysis of Yinhuang Medicinal Broth and Its Membrane Fraction

目的从宏观探讨银黄水煎液在膜分离前后的不同,为膜系统的合理性提供实验依据。方法运用红外光谱分析的方法对银黄水煎液及其膜分离物吸收峰峰位、峰高、图谱进行相关系数比较,从谱图整体分析,判断膜分离效率。结果银黄水煎液和膜分离终产物相同峰位较多,相关系数为0.8327。结论银黄水煎液经两种膜除杂、浓缩后,整体成分损失少,膜系统选择合理。

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.
