摘　　要：建立了一种利用荧光分光光度计检测干红葡萄酒中白藜芦醇的新方法,探讨了白藜芦醇荧光光谱检测的最佳条件,其激发波长和发射波长分别是346.00nm和384.00nm。白藜芦醇产生的荧光强度与浓度在0～1.68×10-5mol/L的范围内具有良好的线性关系,检测限为8.14×10-10mol/L。A new fluorometric method for determining the content of resveratrol in red wine was developed. The optimal condition of fluorosence determination for resveratrol was established. The excitation and emission wavelengths are 346.00 nm and 384.00 nm. The linear relationship between the fluorosence intensity and the concentration of resveratrot was over the range of 0-1.68×10^-5 mol/L,a detection limit was 8.14×10^-10 mol/L. The method is simple, rapid and sensitive.
