摘 要:目的:建立HPLC法测定风湿安泰片申马兜铃酸A的方法。方法:采用RP-HPLC法测定。用ShimadzuC18色谱柱(250mm×4.6mm,5μm),以甲醇-水-冰醋酸(59:40:1)为流动相,流速为lml/min,检测波长250nm,柱温为室温,进样量为10μ1。结果马兜铃酸A的保留时间约为32分钟,与其他峰的分离度大于1.5。马兜铃酸A的线性范围为1.038μg/ml-127.6μg/ml,7=0.9998,最低检测限为5.34×10^-3μg(信噪比为3:1),平均回收率为98.682%(n=5)。结论该方法简便快速,结果准确可靠,可用于风湿安泰片中马兜铃酸A的测定,马兜铃酸A未检出。Abstract Aim: To establish a method for testing of Aristolochie Acid A in Fengshi Antai Tablets. Methods: HPLC was adopted for analysis with a Shimadzu C 18 column (250mm ×4.6mm,5μm), a mobile phase consisting of methanol : water : glacial acetic acid (59:40:1) and eluted at 1ml/min and a detection wavelength at 250nm. Results: The retention time for Aristolochic Acid A was about 32 min. The resolution was over 1.5.with other peaks. The linear range for Aristolochic Acid A was between 1.038 μ g/ml-127.6μg/ml and the limit of detection was 5.34×10^-3 μg. Conclusion: The method was simple, rapid and accurate
