摘要: | 目的:建立同时测定小儿感冒颗粒中(R,S)-告依春、绿原酸、木犀草苷和异绿原酸A含量的方法。方法:采用高效液相色谱法。色谱柱为Hedera C18,流动相为乙腈-0.1%甲酸(梯度洗脱),流速为 1.0 ml/min,检测波长为254 、330、370 nm ,柱温为40 ℃,进样量为5 μl。结果:(R,S)-告依春、绿原酸、木犀草苷和异绿原酸A的检测质量浓度线性范围分别为6.6~105 μg/ml(r=0.999 9)、9~140 μg/ml(r=0.999 9)、9~144 μg/ml(r=0.999 8)、9~138 μg/ml(r=0.999 6);定量限分别为330、450、450、450 ng,检测限分别为66、90、90、90 ng;精密度、稳定性、重复性试验的RSD<3%;加样回收率分别为 95.01%~98.77%(RSD=1.48%,n=6)、95.14%~ 98.91%(RSD=1.52%,n=6)、95.11%~ 97.54%(RSD=0.93%,n=6)、95.58%~ 99.63%(RSD=1.73%,n=6)。结论:该方法操作简便、结果准确,适用于测定小儿感冒颗粒中(R,S)-告依春、绿原酸、木犀草苷和异绿原酸A 的含量。 |
ABSTRACT: | OBJECTIVE: To establish a method for the simultaneous determination of (R,S)-goitrin, chlorogenic acid, luteoloside and isochlorogenic acid A in Xiaoer ganmao granule. METHODS: HPLC was performed on the column of Hedera C18 with mobile phase of acetonitrile-0.1% formic acid aqueous at a flow rate of 1.0 ml/min, the detection wavelength was 254 nm, 330 nm and 370 nm, column temperature was 40 ℃, and the injection volume was 5 μl, RESULTS: The linear range was 6.6-105 μg/ml for (R,S)-goitrin (r=0.999 9), 9-140 μg/ml for chlorogenic acid (r=0.999 9),9-144 μg/ml for luteoloside (r=0.999 8) and 9-138 μg/ml for isochlorogenic acid A (r=0.999 6); the limits of quantitation were 330 ng, 450 ng, 450 ng and 450 ng, limits of detection were 66 ng, 90 ng, 90 ng and 90 ng, respectively; RSDs of precision, stability and reproducibility tests were lower than 3%; recoveries were 95.01%-98.77%(RSD=1.48%,n=6),95.14%-98.91%(RSD=1.52%,n=6), 95.11%-97.54%(RSD=0.93%,n=6) and 95.58%-99.63%(RSD=1.73%,n=6). CONCLUSIONS: The method is simple and accurate, and suitable for the simultaneous determination of (R,S)-goitrin, chlorogenic acid, luteoloside and isochlorogenic acid A in Xiaoer ganmao granule. |
