摘 要: 摸索了一种基于高效液相色谱仪快速测定龙眼果实腺苷三磷酸(ATP)、腺苷二磷酸(ADP)、腺苷一磷酸(AMP)含量的方法。该方法利用磷酸盐缓冲液(pH7.0)作为单一流动相,流速设定为1 mL/min,停止时间13 min,检测波长254 nm,无参比波长。ATP、ADP和AMP浓度在5~50 mg/L范围内与相应的色谱峰面积呈完美的直线关系(决定系数R2均为1.000),回收率95.2%~97.5%,保留时间分别为8.651、9.844和11.457 min。该方法测定结果表明,果实腺苷含量水平分别为30.0、6.5和2.0μg/g,能荷值为0.86。 A rapid method using high performance liquid chromatography was explored to determine the levels of adenosine triphosphate,adenosine diphosphate,adenosine monophosphate in longan fruit.The method used 0.1 mol/L KH2PO4(pH7.0) as the single mobile phase with a flow rate of 1 mL/min,stop time 13 min,the detection wavelength 254 nm,without reference wavelength.The retention time for ATP,ADP and AMP was 8.651,9.844 and 11.457 min,respectively.Within 0~50 mg/L,ATP,ADP and AMP concentrations all displayed perfect linear correlation(R2= 1.000) with their peak areas.The recovery rate reached 95.2% ~97.5%.This method was applied to determine levels of adenosine phosphates in young longan fruit,and the results showed that the average contents of ATP,ADP and AMP were 30.0,6.5 and 2.0 μg/g,respectively,with an energy charge of 0.86 in young fruit.
