Fingerprint research and application for semen coicis

  • Zhejiang Institue for Drug contral, Hangzhou 310004, China

  • Received Date: 2003-10-28
  • OBJECTIVE To establish the fingerprint method for semen coicis. METHODS The Discovery® C18column with acetonitrile-ichloromethanol(59:41)as the mobile phase was used in HPLC-ELSD. The flow rate was 0.5mL/min and ELSD tube temperature is 70℃. The flow rate of Nitrogen is 1.2L/min. RESULTS:There are 7 mostly chromatogram in the fingerprint of semen coicis,the relative standard deviation(RSD)of relative retain time for reproducibility was not more than 0.3%,for precision was not more than 0.1%.the relative standand deviation(RSD)of relative peak area for reproducibility was not more than 1.8%,for precision was not more than 2.0%,and the fingerprint for semen coicis of different producing area is very stabilization. CONCLUSION The method is simple,accurate with a good reproducibility and can be used as a quantitative analysis method for semen coicis.
