Optimization of extraction technology of baicalin in radix scutellariae by RP-HPLC

  • Certification Committee for Drugs of Beijing Drug Administration,Beijing 100053,China

  • Received Date: 2008-03-28
  • Objective:To study the extraction technology of baicalin in radix scutellariae.Methods:The L9（34） orthogonal table was employed to speculate the influence factors of the extraction by means of inspecting alcohol concentration,extracting time and sol- vent volumn,which were the major three influenec factors.Then intiutive analysis and variance analysis were used to review the index of baicalin contents,by which the optimum extraction technology could be selected.Results:The optimum extraction technology were 12 times of 50% alcohol,hot reflux extraction and extracting for 1 time and 3 hours each time.Conclusion:This optimum extradion process of baicalin in radix scutellariae is simple and repeatable and it can be used in industrial production.
