摘  要:目的:建立同时测定气滞胃痛颗粒中白芍药苷、芍药苷、柚皮苷和甘草酸含量的高效液相色谱法。方法:采用Agilent Zorbax SB-C18柱(250 mm×4.6 mm,5 μm),柱温30 ℃;流动相为水(0.2%醋酸)-乙腈(0.2%醋酸),线性梯度洗脱,流速为1.0 mL·min-1;检测波长为230 nm(0-15 min),284 nm(15-20 min),254 nm(20-35 min)。结果:白芍药苷、芍药苷、柚皮苷、甘草酸浓度分别在15.1-226 μg·mL-1(r=0.9998),25.6-383 μg·mL-1(r=0.9998),27.7-277 μg·mL-1(r=0.9998),9.43-47.2 μg·mL-1(r=0.9998)范围内线性关系良好。低、中、高3个浓度的平均加样回收率分别为97.4%-101%(RSD为0.8%-1.7%),96.8%-99.7%(RSD为1.4%-2.6%),97.3%-100%(RSD为1.9%-2.4%)。结论:本方法简便、准确,重复性好,可以为气滞胃痛颗粒的质量控制提供依据。Objective:To establish an HPLC method for the simultaneous determination of albiflorin, paeoniflorin, naringin and glycyrrhizin in Qizhiweitong granules.Method:The chromatography was performed on a Zorbax SB-C18 column(250 mm×4.6 mm, 5 μm) with a mobile phase ofwater(containing 0.2% acetic acid)-acetonitrile(containing 0.2% acetic acid) and linear gradient elution. The flow rate was 1.0 mL·min-1. The column temperature was 30 ℃. The detection wavelength was 230nm from 0 to 15 min, 284nm from 15 to 20 min and 254nm from 20 to 35 min.Results:The calibration curves of albiflorin,paeoniflorin, naringin and glycyrrhizin were linear in the ranges of 15.1-226μg·mL-1(r=0.9998), 25.6-383 μg·mL-1(r=0.9998), 27.7-277 μg·mL-1(r=0.9998) and 9.43-47.2 μg·mL-1(r=0.9998)respectively.The mean recoveries of low, middle and high concentrations of the four componentswere 97.4%-101%(RSD=0.8%-1.7%), 96.8%-99.7%(RSD=1.4%-2.6%), 97.3%-100%(RSD=1.9%-2.4%).Conclusion:The method is simple and accurate, which can be used in the quality control ofQizhiweitong granules.
