Abstract:Objective: To establish an HPLC method for the determination of adenosine in Fritillaria ussuriensis Maxim. Method: Inertsil ODS-SP (250 mm ×4. 6 mm,5μm) column was used with aqueous solution containing 7 % aeetonitrile as mobile phase ,the flow rate was 1.0 ml · min^- 1 , temperature was room temperature, and detection wavelength was at 260nm. Result: The linear range of adenosine was 0. 04-0. 24 μg ( r = 0. 999 9 ) with average recovery of 96. 32 % and RSD of 1. 15% ( n = 5 ) . Conclusion: The method is simple, accurate and can be used to control the quality of FritiUaria ussuriensis Maxim .
Keywords:FritiUaria ussuriensis Maxim.  Adenosine  HPLC
