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HederaC。流动相为乙腈-0.1%甲酸(梯度洗脱),流速为1.0ml/min,检测波长为254、330、370nm,柱温为40℃,进样量为5ul。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6.6~105μg/m1(r=0.9999)、9~140μg/ml(r=0.9999)、9~144μg/m1(,=0.9998)、9~138gg/ml(r=0.9996);定量限分别为330、450、450、450ng,检测限分别为66、90、90、90ng;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。OBJECTIVE: To establish a method for the simultaneous determination of (R, S)-goitrin, chlorogenic acid, luteolo- side and isochlorogenic acid A in Xiaoer ganmao granule. METHODS : HPLC was performed on the column of Hedera C18 with mo- bile 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 5μl, RESULTS: The linear range was 6.6-105 gg/ml for (R,S)-goitrin (r=0.999 9), 9-140 gg/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 rig, 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=l.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=l.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.
