  • Received Date: 2002-06-24
  • OBJECTIVE To establish a method to determine the content of total astragalosides in Fuzhengpingxiao capsules, and primary research about the extraction has been done with this method. METHODS Three different methods were used to prepare the crude extractive liquid, which were extracted by pure water,60% alcohol and deposited by alcohol after extracted by pure water. The crude extractive liquid was extracted by n-butanol saturated by water. Colorimetric analysis was used to determine the content of total astragalosides. RESULTS The mean content of total astagalosides extracted by three different methods were 0.26%,0.34% and 0.16%,respectively. The amount of the total astragalosides extracted by 60% alcohol was the highest. CONCLUSION The method can be used to control the quality of Fuzhengpingxiao capsules.
