HPLC测定杜仲腰痛浓缩丸中阿魏酸含量
Determination of Ferulic Acid in DuZhong YaoTong Concentrated Pills by HPLC
【摘要】 目的:采用高效液相色谱法测定杜仲腰痛浓缩丸中阿魏酸含量。方法:色谱柱:Symmetry C18柱(5μm,4.6 mm×250 mm);流动相:乙腈-0.085%磷酸水溶液(17∶83)(V/V);流速:1.0 mL/min;检测波长:316 nm。结果:阿魏酸在2.02~20.02mg/L之间线性关系良好(r=0.9997,n=6),平均加样回收率为98.09%,RSD为1.02%。结论:本法操作简便,结果准确,可用于杜仲腰痛浓缩丸的质量控制。
【Abstract】 Objective: To determine the contents of ferulic acid in DuZhong YaoTong concentrated pills by HPLC. Methods: Chromatographic column: Symmetry C18 column(5 μm, 4.6 mm×250 mm); mobile phase: acetonitrile-0.085% phosphoric acid solution(17:83)(V/V); the flow rate: 1.0mL/min; detection wavelength: 316nm. Results: Ferulic acid showed better linear relationship in the range between 2.02 and 20.02 mg/L(r=0.999 7, n=6), average recovery was 98.09%, RSD was 1.02%. Conclusion: The method, simple and accurate, could be used for quality control of DuZhong YaoTong concentrated pills.
