Objective To optimize the water extractive process of Guben Zhike Electuary. Methods To arrange experiments with uniform design for optimizing suitable extractive proces, with the content of polysaccharide and astragaloside Ⅳ as the detecting indexes, inspecting the extacting times, lasting time and additional water which would affect the extraction rate of the two effective components. Result The best process was that water as extraction solvent, extracted for three times with two hours each time, and the amount of water added up to nine times of herbs. Conclusion The best process could extract most of the effective components out of the herbs, which is scientific.

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.
