【摘要】 目的采用分光光度法测定冠心康片中总黄酮的含量。方法以芦丁为标准品建立标准曲线,检测波长为510nm。结果回归方程为C=-0.00142+0.8558A,在0.0751～0.6004mg内呈良好线性关系(r=0.9999),平均加样回收率为99.42%,RSD为1.64%(n=5)。不同批号冠心康片每片总黄酮平均含量为0.3631mg。结论该方法简便、准确,适用于冠心康片的质量分析检验。更多还原

【Abstract】 OBJECTIVE To determine the contents of total flavonoids in Guanxinkang tablet by spectrophotometry.METHODS Taking rutin as the control to make standard curve,the detective wavelength was 510 nm.RESULTS Regression equation was C=-0.001 42+0.855 8A(r=0.999 9).The linear concentration was in the range of 0.075 1-0.600 4 mg for rutin.The average recovery was 99.42%,RSD was 1.64%(n=5).The average contents of total flavonoids from Guanxinkang tablet with different numbers was 0.363 1 mg.CONCLUSION The method is simple and accurate,it can be used for quality control of Guanxinkang tablet.更多还原
