Abstract:
Objective To discuss the probability of extracting the effective part of Yinhuang prescription with membrane separation method. Methods To extract and concentrate Yinhuang decoction with amb-class UF and first class NF, baicalin and chlorogenic acid were detected with HPLC, and polysaccharide with anthrone agent colorimetry. Results The content of polysaccharide in final membrane fraction was 3.41 mg/mL. The diversion ratio of baicalin and chlorogenic acid from primal decoction was 77.24%, 79.02%. Conclusion The effective part of Yinhuang decoction can be extracted with membrane separation method. Multiple active components including polysaccharide were retained and the method is simple.
