HPLC法测定寒湿痹颗粒中马兜铃酸A

压铸机料筒的设计ＨＰＬＣ法测定寒湿痹颗粒中马兜铃酸Ａ

圆极化天线

目的：建立测定寒湿痹颗粒中马兜铃酸A的高效液相谱的分析方法。方法：谱柱为Agilent Zorbax SB-C18 柱（250 mm×4.6 mm，5 μm），以甲醇-1%冰醋酸水溶液（55∶45）为流动相，流速为1.0 ml/min，检测波长为315 nm，建立HPLC检测方法。结果：马兜铃酸A峰面积与进样量在0.010 2～0.102 5 μg范围内具有良好的线性关系（r=1.000）。平均回收率为99.3％（n=6），RSD=0.41％。本方法按信噪比为2∶1计算最低检测限为2 ng。结论：该方法简单，可靠，检测限低，重现性好，可用于寒湿痹胶囊中马兜铃酸A的限量检测。

超声波放大器[Abstract] Objective: To establish a method for the determination of aristolochic acid A in Hanshibi Granules by HPLC Methods: The column was Agilent Zorbax SB-C18, mobile phase was methanol–1% glacial acetic acid (55∶45).The flow rate was set at 1 ml/min,detection wavelength was set at 315 nm. Resultes: The calibration curve was linear at the range of 0.010 2-0.102 5 μg (r=1.000). The average recovery was 99.3% (RSD=0.41%). The limit of detection of aristolochic acid A was 2 ng. Conclusion: The metho
