摘要:

应用高效液相色谱法建立浓缩枣汁中环磷酸腺苷(cAMP)和环磷酸鸟苷(cGMP)的检测方法。结果表明,cAMP 和cGMP 在0~50mg/L 线性范围内均具有良好的线性关系,方法检出限(LOD)为0.1mg/kg;两种环核苷酸的平均回收率在82.2%~99.3% 之间,相对标准偏差(RSD)在2.1%~10.9% 之间。本方法可有效地用于浓缩枣汁中cAMP 和cGMP 含量的测定。

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
