【摘要】 确定了新鲜米糠中阿魏酸的最佳提取工艺。采用高效液相色谱法对提取产品的定性检测,荧光分光光度法对提取产品的定量检测。阿魏酸在0.2～2.2μg/ml浓度范围内呈良好的线性关系,相关系数为0.99957,平均回收率为99.0%。此法具有准确、简便、快速、灵敏等优点。更多还原

【Abstract】 To optimize the extraction process for ferulic acid from rice bran. HPLC was used as the quality analysis method, and spectrofluorimetry as the quantity analysis method. The linear range of the ferulic acid is 0.2～2.2μg/ml, and relationship coefficient 0.99957. The average recovery is 99.0%. It is accurate, simple, rapid and sensitive to determine the ferulic acid with the fluorescence method.更多还原
