摘　　要：确定了新鲜米糠中阿魏酸的最佳提取工艺.用高效液相色谱法对提取产品作定性检测,用荧光分光光度法对提取产品作定量检测.阿魏酸在0.2～2.2 μg/mL浓度范围内呈良好的线性关系,相关系数为0.99958,平均回收率为99.0%.此法具有准确、简便、快速、灵敏等优点.To optimum the extraction process for ferulic acid from rice bran. HPLC was used as the quality analysis method, and spectrofluorimetry was used as the quantity analysis method. The linear range of the ferulic acid was 0.2-2.2ug/mL, relationship coefficient was 0.99958. The average recovery was 99.0%. It is accurate, simple, rapid, sensitive to determine the ferulic acid with the fluorescence method.
