摘要: 利用化学计量学二阶校正方法结合高效液相色谱对枣花蜜中10种酚酸类物质的快速定量分析进行了研究。首先通过验证样本研究了所建立模型的准确性。结果显示：10种酚酸类物质的线性相关系数（R）为0.9982~0.9999，平均回收率为97.6%~101.1%，说明所建立的模型稳定可靠。其次，通过模拟蜂蜜试验，确定了固相萃取柱的种类及操作条件（HLB柱，酸化水淋洗，甲醇洗脱）。最后，利用模拟蜂蜜得到的最优条件结合化学计量学二阶校正方法，测定了枣花蜜中10种酚酸类物质的含量，并测得其加标回收率为62.1%~93.8%，考虑到目标分析物的种类较多，且蜂蜜基质极为复杂，该结果基本满足要求。另外，还利用统计与品质因子验证了试验方法的可靠性，结果令人满意。该方法具有简单、快速等优点，可用于复杂基质中多种目标分析物的同时定量分析。

Abstract: This study aims at the determination of ten phenolic acids in honey using high-performance liquid chromatography-diode array detection (HPLC-DAD) combined with a chemometric second-order calibration method. First, the accuracy of the model was investigated by analysis of the calibration samples and validation samples. Satisfactory results were obtained; the ten phenolic acids exhibited good linearity, and the correlation coefficient (R) was in the range 0.9982-0.9999, with average recoveries of 97.6% to 101.1%, which proved that the model was stable and reliable. Second, the types and operating conditions of the SPE columns were determined by experiments using simulated honey; HLB column was selected, washed with 0.1%(v/v) formic acid aqueous solution, and eluted with methanol. Finally, the phenolic acid contents in jujube flower honey were determined under the optimum conditions for simulated honey. The recoveries of the analytes were 62.1%-93.8%, which met the requirements considering the variety of target analytes and the complexity of the honey substrate. In addition, the efficiency of the method was validated by figures of merit and statistical parameters, including sensitivity (SEN), selectivity (SEL), root-mean-square error of prediction (RMSEP), limit of detection (LOD), and limit of quantification (LOQ); the obtained results were satisfactory. This method is simple, fast, and accurate, and it can be used for the quantitative analysis of the target analytes in complex substrates.
