摘要
目的:建立新保肾片中芦荟大黄素、大黄酸、大黄素、大黄酚和大黄素甲醚的含量测定方法,为生产质量提供保障。方法采用高效液相色谱法测定,色谱柱为Lichrospher-C18柱(250 mm ×4.6 mm ,5μm),流动相为甲醇∶0.1%磷酸溶液(70:30),流速为1.0 ml/min ,柱温为35℃,检测波长为254 nm。结果芦荟大黄素、大黄酸、大黄素、大黄酚和大黄素甲醚分别在2.30~18.4μg/m l ( r=1.0)、2.930~23.44μg/m l ( r=1.0)、5.00~40.0μg/m l ( r=1.0)、14.870~118.96μg/m l (r=0.9998)、7.410~59.28μg/ml(r=0.9999)范围内有良好的线性关系,平均回收率分别为100.16%、102.91%、99.76%、100.32%、100.44%,RSD分别为1.58%、1.27%、1.67%、1.33%、1.03%(n=9)。结论该方法准确易行,便于质量控制。
Objective To establish method of the determination of aloe-emodin ,rhein ,emodin ,chrysophanol and physcion in Xinbaoshen tablet ,for the production of quality protection .Methods HPLC was performed on a Lichrospher-C18 column (250 mm × 4 .6mm ,5 μm)with the mobile phase of methanol-0 .1% H3 PO4 (70:30) .The flow rate was 1 .0 ml/min ,the col-umn temperature was at 35 ℃ and the detection wavelength was 254 nm .Results The linear rang of aloe-emodin ,rhein ,emod-in ,chrysophanol and physcion were obtained between 2 .30-18 .4 μg/ml ( r= 1 .0) ,2 .930-23 .44 μg/ml( r= 1 .0) ,5 .00-40 .0 μg/ml ( r=1 .0) ,14 .870-118 .96μg/ml( r= 0 .9998 ) and 7 .410-59 .28 μg/ml(r=0 .999 9) ,the average recoveries were 100 .16% ,102 .91% ,99 .76% ,100 .32% ,100 .44% ,RSD were 1 .58% ,1 .27% ,1 .67% ,1 .33% ,1 .03% (n=9) .Conclusion The improved method was accurate and feasible which could be used convenient in quality control .
