Abstract:

A HPLC method was developed for the simultaneous determination of cAMP and cGMP in commerical jujube juice concentrate. Both concentrations of cAMP and cGMP exhibited a good linear relationship with peak area in the range of 0-50 mg/L. The limits of detection (LOD) of the method to them were both 0.1 mg/kg. The spiked recoveries at three levels (1, 10 and 20 mg/L) ranged from 82.2% to 99.3%, with a RSD between 2.1% and 10.9%. The method is suitable for the effective determination of cAMP and cGMP in jujube juice concentrate.

Key words: HPLC, jujube juice concentrate, cyclic nucleotides, detection method
