【摘要】 目的 :建立高效液相色谱法测定鼻复康口服液中黄芩苷含量的方法。方法 :以ODSC18 为色谱柱 ,流动相为甲醇 -水 -冰醋酸 (45∶55∶1 5) ,检测波长为274nm ,流速为1 0ml/min。结果 :黄芩苷进样量在0 215μg～4 3μg 范围内线性关系良好 (r=0 9995) ,平均加样回收率为99 44 % (RSD=0 79 % ,n=5)。结论 :本法简便、快速、灵敏 ,可用于该制剂的质量控制更多还原

【Abstract】 OBJECTIVE:To establish a HPLC method for determination of the content of baicalin in Bifukang oral liqˉuid.METHODS:The ODS C 18 column was used with methanol-water-glacial acetic acid(45∶55∶1.5)as mobile phase,and deˉtective wavelength was274nm,the flow rate was1ml/min.RESULTS:Within the range of0.215μg～4.3μg,baicalin presented a fine linear relationship between amount and peak area(r=0.9995).The average recovery was99.44%(RSD=0.79%,n=5). CONCLUSION:This HPLC method is convenient,rapid and accurate,and can be used for quality control in the production of Bifukang oral liquid.更多还原
