摘要: 【目的】建立一种以ASE-HPLC法为基础的快速、高效测定果园土壤酚酸类物质含量的新方法。【方法】以苹果特征酚酸类物质根皮苷为例,采用加速溶剂提取法(accelerated solvent extraction, ASE)和高效液相色谱法(high performance liquid chromatography, HPLC)相结合的测定方法,对萃取溶剂、萃取温度、压力和循环数等参数进行优化,寻找ASE法提取酚酸类物质的最佳工艺条件。【结果】ASE法提取苹果园土壤酚酸类物质的最佳工艺条件为:先以无水乙醇为萃取溶剂,再以甲醇为萃取溶剂,提取温度为120℃,压强为10.3 MPa,循环2次,每次静态提取时间为5 min,吹扫体积为60%,吹扫时间为90 s。【结论】该方法样品处理简单,具有良好的重现性和线性,相关性系数均达到0.99,回收率在83%—98%之间,检测限为1.3×10-4—2.5×10-2 μg•mL-1。ASE-HPLC法是一种简便、快速和高效测定土壤酚酸含量的新方法,具有推广应用价值。

Abstract: 【Objective】To establish a new protocol based on the ASE-HPLC method, which could determine the content of phenolic acids in orchard soil rapidly and efficiently.【Method】Phlorizin was set as an sample for analysis, which is one of the characteristic phenolic acids in apple orchard soil. Accelerated solvent extraction (ASE) combined with high performance liquid chromatography (HPLC) was used to assess it. Specifically, the parameters of extraction solvent, extraction temperature, pressure and number of cycles were optimized, aiming at exploring the optimal conditions of ASE extraction for phenolic acids.【Result】The optimal conditions of ASE extraction for phenolic acids were as follows: Ethanol as extraction solvent initially, and methanol was the subsequent extraction solvent,extraction temperature at 120℃, a pressure of 10.3 MPa, 2 cycles, every 5 min static time, 60% purge volume, and purge time for 90 s. 【Conclusion】The process was more simple, and with good reproducibility and linearity, correlation coefficient up to 0.99, recovery efficiency between 83% and 98%, detection limit to the amount of 1.3 × 10-4 -2.5 × 10-2 μg•mL-1. ASE-HPLC is an accurate and rapid new protocol to mensurate phenolic acids, which is an improved and practical method.
