篇名: | HPLC法同时测定益肤丸中香豆素类化合物的含量 |
TITLE: | |
摘要: | 目的:建立同时测定益肤丸中香豆素类化合物含量的方法。方法:采用高效液相色谱法。色谱柱为Inertsil ODS-3,流动相为乙腈-水(49 ∶ 51,V/V), 流速为1.0 ml/min,检测波长为320 nm,柱温为30 ℃,进样量为20 μl。结果:蛇床子素、异欧前胡素和二氢欧山芹醇当归酸酯检测质量浓度线性范围分别为5.16~206.4 μg/ml(r=0.999 9)、37.40~1 495.89 μg/ml(r=0.999 9)、9.95~318.34 μg/ml(r=0.999 9);精密度、稳定性、重复性试验的RSD<3.0%;加样回收率分别为96.05%~103.19%(RSD=2.18%,n=9)、96.90%~103.09%(RSD=2.07%,n=9)、95.50%~103.57%(RSD=2.15%,n=9)。结论:该方法操作简便,精密度、稳定性、重复性较好,可用于益肤丸中香豆素类化合物含量的同时测定。 |
ABSTRACT: | OBJECTIVE: To establish a method for the simultaneous determination of coumarin compounds in Yifu pill. METHODS: HPLC was performed on the column of Inertsil ODS-3 with mobile phase of acetonitrile-water(49 ∶ 51,V/V) at a flow rate was 1.0 ml/min, the detection wavelength was 320 nm, column temperature was 30 ℃, injection volume was 20 μl. RESULTS: The linear range was 5.16-206.4 μg/ml for osthole (r=0.999 9),37.40-1 495.89 μg/ml for isoimperatorin(r=0.999 9) and 9.95- 318.34 μg/ml for columbianadin (r=0.999 9); RSDs of precision, stability and reproducibility tests were lower than 3.0%; recoveries were 96.05%-103.19%(RSD=2.18%,n=9) for osthole,96.90%-103.09%(RSD=2.07%,n=9) for isoimperatorin,95.50%-103.57%(RSD=2.15%,n=9) for columbianadin. CONCLUSIONS: The method is simple with good precision, stability and reproducibility, and can be used for the simultaneous determination of coumarin compounds in Yifu pill. |
