目的:建立快速同时测定银黄胶囊中黄芩苷和绿原酸的含量测定方法。方法 HPLC 等度洗脱法。色谱柱:C18柱;流动相为甲醇︰水︰磷酸(45∶55∶0.2);流速:1.0 mL /min ;检测波长:328 nm ;柱温:30℃。结果本法可同时测定黄芩苷和绿原酸的含量。黄芩苷在24.20μg/mL ~242.0μg/mL 范围内线性关系良好( R2=0.9992),平均回收率为99.72%;绿原酸在2.200μg/mL ~44.00μg/mL 范围内线性关系良好( R2=0.9999),平均回收率为99.63%。结论该方法操作简便,成本低,工作效率高。
目的:建立快速同時測定銀黃膠囊中黃芩苷和綠原痠的含量測定方法。方法 HPLC 等度洗脫法。色譜柱:C18柱;流動相為甲醇︰水︰燐痠(45∶55∶0.2);流速:1.0 mL /min ;檢測波長:328 nm ;柱溫:30℃。結果本法可同時測定黃芩苷和綠原痠的含量。黃芩苷在24.20μg/mL ~242.0μg/mL 範圍內線性關繫良好( R2=0.9992),平均迴收率為99.72%;綠原痠在2.200μg/mL ~44.00μg/mL 範圍內線性關繫良好( R2=0.9999),平均迴收率為99.63%。結論該方法操作簡便,成本低,工作效率高。

Objective To establish a rapid determination of silver yellow capsules of baicalin and chlorogenic acid method . Methods Simultaneous determination of baicalin and chlorogenic acid , column ∶ C18 column ; mobile phase ∶ methanol ∶ water ∶ phosphoric acid ( 45 ∶ 55 ∶ 0 .2) ; flow rate ∶ 1 .0 mL/ min ; detection wavelength ∶ 328 nm ; column temperature ∶ 30 ℃ . Results The simultaneous determination of baicalin and chlorogenic acid . Baicalin in within the range of 24 .20 μg/ mL ~ 242 .0 μg/ mL into a good linear relationship between peak area ( R2 =0 .999 2) , the average recovery was 99 .72% ; chlorogenic acid in the range of 2 .200 μg / mL ~ 44 .00 μg/ mL peak area as well linear relationship ( R2 = 0 .999 9) , the average recovery was 99 .63% . Conclusion The method is simple and increases efficiency , can be used as the determination of silver yellow capsule method .
