无机陶瓷膜微滤技术精制7种根及根茎类中药水提液的研究

Study on Refining of Decoctions of 7 Medicinal Materials of Radix and Rhizome by Microfiltration of Inorganic Ceramic Membrane

目的 :对无机陶瓷膜微滤技术精制根及根茎类中药水提液的效果进行初步评价。方法 :用孔径为 0 .2 μm的无机陶瓷膜对 7种根及根茎类常用中药的水提液进行微滤 ,对水提液微滤前后性状、总固体、指标成分等的变化进行对比分析。结果 :中药水提液微滤前均为浑浊液体 ,微滤后成为颜色变浅的澄明液体 ,其总固体去除率为 15～ 38% ,有效成分损失率一般小于总固体去除率。结论

Objective: To evaluate effect of refining of decoctions of medicinal materials of radix and rhizome by microfiltration of inorganic ceramic membrane. Methods: The decoctions of 7 medicinal materials of radix and rhizome were processed by inorganic ceramic membrane, and the whole solids and effective ingredients were determined. Results: The decoctions of Chinese traditional medicine became clear after microfiltration. The whole solids were decreased by 15～38%, and the lost rate of effective ingredients was lower than that of whole solids. Conclusion: The microfiltrating technology of inorganic ceramic membrane can make decoctions of Chinese Traditional Medicine clear.
