Experimental Studies On Semi-Bionic Extraction(SBE) Of Baitouweng Decoction

Objective:To optimize the method of Semi-Bionic Extraction. Method :Take the fraxetin, berberine, HPLC total peaareas of Baitouweng and dry extract as index,optimize the SBE technical conditions Baitouweng Decoction by even design. On the basis of the work above, compare Semi-Bionic Extraction (SBE) with Water Extraction (WE),research the identification method of Baitouweng Decoction Result: First , the extraction condition of Baitouweng Decoction is pH in turn:6.0,7.5,8.5; Time: 2h,lh,lh; Semi-Bionic Extract method is beter extract method than Water Extract method. Conclusion: Semi-Bionic Extract method( SBE ) may replace the method of Water Extract method(WE), HPLC can be used as the identification method of the Baitouweng Decoction...
