用毛细管电泳紫外检测法同时测定了复方芦丁片中芦丁和抗坏血酸的含量 ,研究了各种条件的影响 ,得到了优化的实验条件 ,在 30 mmol/L Na2 B4 O7-H3BO3( p H7.5 0 )缓冲溶液中 ,芦丁和维生素 C在 1 3min内得到了良好的分离 ,芦丁和维生素 C分别在 0 .5～ 0 .0 0 5 mg和 5 .0～ 0 .0 5 mg浓度范围内与电泳峰高呈现良好线性关系 ,检测下限分别为 0 .0 0 2 mg和 0 .0 1 mg,应用于实际样品的测定 The contents of rutin and ascorbic acid in compound rutin tablets were determined simultaneously by capillary electrophoresis with ultraviolet detection. The effects of various conditions were studied. The optimal experimental conditions were obtained. The optimum conditions were 30 mmol / L Na2B4 O7-H3BO3 (p H7. 5 0) buffer solution, rutin and vitamin C in 13min get a good separation, rutin and vitamin C were 0. 05 ~ 0 0 05 mg and 5 0 ~ 0. 0 5 mg concentration Within the range and electrophoresis peak height showed a good linear relationship, the detection limit were 0. 02 0 mg and 0.1 1 mg, applied to the actual sample determination
