【摘要】 目的建立以高效液相色谱法测定肺炎Ⅰ号合剂中黄芩苷含量的方法。方法色谱柱为ODS C18,流动相为甲醇-0.06%磷酸(43∶57),检测波长为278nm,柱温为25℃,流速为1.0ml/min。结果黄芩苷进样量在0.1875μg~1.5μg范围内与峰面积积分值呈良好的线性关系(r=0.9998);平均加样回收率为99.63%(RSD=1.00%,n=6)。结论本方法简便、准确、重现性好,可用于该制剂的质量控制。更多还原

【Abstract】 OBJECTIVE:To establish a HPLC method for the content determination of baicalin in Pneumonia I mixture.METHODS:The assaying was conducted on a ODS C 18 column with methol-0.06%H 3 PO 4 (43∶57)as mobile phase,the detection wavelength was278nm,the column temperature was25℃and the flow rate was1.0ml/min.RESULTS:The linear concentration range of baicalin was0.1875μg～1.5μg(r=0.9998)with average recovery rate at99.63%(RSD=1.00%,n=6).CONCLUSION:This method is simple,accurate and reproducible,and it can be used for the quality control of baicalin.更多还原
