英文标题:
中文摘要: 目的:建立同时测定荨麻疹丸中芍药苷、黄芩苷和欧前胡素含量的方法。方法:采用高效液相色谱法。色谱柱为Alltima C18,流动相为甲醇-水-磷酸(55 ∶ 45 ∶ 0.2,V/V/V),流速为1.0 ml/min,检测波长为230 nm(芍药苷)、280 nm(黄芩苷)、300  nm(欧前胡素),柱温为30 ℃,进样量为10 μl。结果:芍药苷、黄芩苷和欧前胡素的检测质量浓度线性范围为5.40~54.0 μg/ml(r=0.999 8)、11.29~112.9 μg/ml(r=0.999 7)、24.95~249.5 μg/ml(r=0.999 9);定量限分别为5.4、11.2、30.0 ng,检测限分别为1.8、2.8、7.5 ng;精密度、稳定性、重复性试验的RSD<2%;加样回收率分别为95.88%~98.33%(RSD=0.95%,n=6)、96.86%~99.96%(RSD=1.20%,n=6)、98.07%~100.55%(RSD=0.92%,n=6)。结论:该方法简便、准确、专属性强、重复性好,可用于测定荨麻疹丸中黄芩苷、芍药苷和欧前胡素的含量。
英文摘要: OBJECTIVE: To establish a method for the simultaneous determination of paeoniflorin, baicalin and imperatorin in Urticaria pill. METHODS: HPLC was performed on the column of Alltima C18 with mobile phase of methanol-water-Phosphoric acid (55 ∶ 45 ∶ 0.2,V/V/V) at a flow rate of 1.0 ml/min, the detection wavelength was 230 nm for paeoniflorin, 280 nm for baicalin and 300 nm for imperatorin, column temperature was 30 ℃, and the volume injection was 10 μl. RESULTS: The linear range was 5.40-54.0 μg/ml for paeoniflorin (r=0.999 8),11.29-112.9 μg/ml for baicalin(r=0.999 7) and 24.95-249.5 μg/ml for imperatorin (r=0.999 9), respectively; the linit of quantitation were 5.4、11.2、30.0 ng,the lirnit of detection were 1.8、2.8、7.5 ng; RSDs of precision, stability and reproducibility tests were lower than 2%; recoveries were 95.88%-98.33% (RSD=0.95%,n=6),96.86%-99.96%(RSD=1.20%,n=6) and 98.07%-100.55%(RSD=0.92%,n=6), respectively. CONCLUSIONS: The method is simple and accurate with strong specificity and good reproducibility, and can be used for the simultaneous determination of paeoniflorin, baicalin and imperatorin in Urticaria pill.
