摘要
目的:建立同时测定鳖甲煎丸中芍药苷、黄芩苷、丹皮酚3种有效成分含量的HPLC方法。方法采用Agilent Zorbax Eclipse XDB-C18色谱柱(5μm,4.6mm×150mm),流动相为乙腈(A)和0.1%磷酸水溶液(B),梯度洗脱,流速1.0mL/min;检测波长240、274nm,柱温35℃。结果芍药苷、黄芩苷、丹皮酚线性浓度范围分别是:1.41~14.11μg/mL(r2=0.9999),7.03~70.32μg/mL(r2=0.9999),1.23~12.32μg/mL(r2=0.9997)对照品线性关系良好,各成分的平均回收率(n=9)分别为:100.84%、99.07%、99.08%.结论该方法准确、可靠、重现性好,可用于鳖甲煎丸提取物的质量控制。
Objective To establish a HPLC method for the determinations of paeoniflorin, baicalin and paeonol in Biejiajian pills. Methods Agilent Zorbax Eclipse XDB C18 column (5μm, 4.6 mm ×150 mm), mobile phase of acetonitrile (A)and 0. 1%phosphoric acid (B). Gradient elution, flow rate of 1.0 mL/min, the detection wavelength of 240nm and 274nm, the column temperature was 35℃. Results The linearity ranges of paeoniflorin, baicalin and paeono was 1.41~14.11μg/mL(r2=0.9999), 7.03~70.32μg/mL(r2=0.9999), 1.23 ~12.32μg/mL(r2=0.9997)respectively. The average recoveries(n=9)were100.84%, 99.07%, 99.08%. Conclusion The results showed that the method can be used to control quality of Biejiajian pills.
