摘要: 旨在建立同时测定花生衣、葡萄皮、苜蓿、虎杖、藜芦等农产品中白藜芦醇含量的高效液相色谱标准化测定方法。色谱分析条件如下:以Waters Atlantis T3- C18 色谱柱(4.6×150mm,3 μm)分离,柱温40℃;以乙腈:0.1%乙酸溶液(体积比为26:74)为流动相,流速1.0 mL/min;采用二极管阵列检测器,检测波长306 nm。花生衣、葡萄皮、苜蓿中白藜芦醇含量的检出限均为0.6 μg/g,定量限均为2.0 μg/g;虎杖、藜芦中白藜芦醇含量的检出限均为7.5 μg/g,定量限均为25 μg/g。方法学考察结果显示符合含量测定要求。该方法操作简便、快速,结果可靠,重现性好,可用来研究农产品中白藜芦醇的含量。

Abstract: A high performance liquid chromatographic (HPLC) standardized method was established to simultaneous determine the content of resveratrol in agricultural products such as peanut skin, grape skin, alfalfa, Polygonum cuspidatum and Veratrum nigrum Linn.. The HPLC conditions were as follows: Waters Atlantis T3 C18 column (4.6 mm i.d.×150 mm, 3 μm) was used at 40℃ with acetonitrile-water containing 0.1% acetic acid (26:74, v/v) as the mobile phase with a flow rate of 1.0 mL/min, diode array detector with the detection at 306 nm. The limits of detection (LODs) and limits of quantification (LOQs) for peanut skin, grape skin and alfalfa were 0.6 μg/g and 2.0 μg/g. LODs and LOQs forPolygonum cuspidatum andVeratrum nigrum Linn. were 7.5 μg/g and 25 μg/g. The results of methodological study demonstrated that the method met the requirements of the determination. The method was simple, fast, accurate and reproducible for the analysis of resveratrol in agricultural products.
