摘要
目的 :建立测定减肥降脂片中大黄酸、大黄素含量的高效液相色谱方法。方法 :分析柱为WatersSymmetryC18 柱(4 6mm×250mm ,5μm) ;流动相为甲醇 -0 1 %磷酸 (90∶10) ;检测波长为440nm ;流速为1 0ml/min ;柱温为30℃。结果 :大黄酸在0 108μg～0 486μg、大黄素在0 180μg～0 480μg范围内呈良好线性关系 ;回收率 :大黄酸为99 7% ,大黄素为98 6;精密度 :大黄酸为1 93 % ,大黄素为2 19%。结论 :本法检测快速 ,定量准确 ,可用于减肥降脂片的定量分析。
OBJECTIVE:To establish a HPLC method for determining the contents of rhein and emodin in Jianfei Jiangzhi tablets.METHODS:Stationary phase was Waters Symmetry C 18 (250mm×4.6mm;5μm),mobile phase was menthol-0.01%H 3 PO 4 (90∶10),detection wavelength440nm,flow rate1.0ml/min and column temperature30℃.RESULTS:There was good linearity in range of0.108μg～0.468μg for rhein and in range of0.180μg～0.480μg for emodin.The average recoveries of rhein and emodin were99.7%and98.6%respectively;RSD were1.93%and2.19%respectively.CONCLUSION:This method is rapid and accurate.It can be applied to effective control of the quality of Jianfei Jiangzhi tablet.
