摘要
为了建立液相色谱法测定抗坏血酸钠盐中糠酸方法，采用液相色谱检测，紫外检测器，C18色谱柱，柱温为30℃，流动相采用乙腈／磷酸盐缓冲溶液。考察了检测方法的检出限、定量限、线性、精密度、稳定性。该方法线性方程为：Y=51403X＋2142．9，在0．5～10μg·mL^-1内，线性关系良好（r=0．9999）。结果表明，该方法适合于抗坏血酸钠盐中糠酸的测定。
In order to establish the determination method of furoic acid in sodium ascorbate by liquid chromatography, HPLC, UV detector, C18 column which temperature was 30℃, mobile phase with acetonitrile/phosphate buffer solution were adopted. The detection limit, limit of quantitation, linearity,precision, stability of the detection method were investigated. The linear equation of the method was Y=51 403 X＋2 142.9,, and the method had a good linear relationship （r= 0.999 9） during 0.5~10 μg·mL^-1.The results showed that this method was suitable for the determination of bran acid in the sodium ascorbate.
