Objective: To establish the determination of adenosine in Ganping Capsules. Methods: HPLC method was developed for the determination of adenosine in Ganping Capsules on Kromasil C 18 (150mm? 4.6mm i.d.) in 0.05mol/L KH 2PO 4 methanol (88∶12, V/V,pH 4.7) as a mobile phase (1.0mL/min). The UV detection wavelength was set at 260nm. Adenosine was extracted with 10% methanol water. Results: The recoveries was 98%～102% and the linear equation was Y=2537.4X+100.81. The correlation coefficient was r =0.9999(n=5). Conclusion: The method is simple, rapid and accurate.
