摘要
目的建立同时测定心脑舒口服液(人参、黄芪、五味子、党参、麦冬)中人参皂苷Rg;人参皂苷Re;人参皂苷Rf;人参皂苷Rb1;人参皂苷Rb2;人参皂苷Rb3;黄芪甲苷的方法。方法采用HPLC—ELSD法;Kromasi]C,s色谱柱;乙腈一水为流动相;体积流量为1mL/min。结果根据回归方程,7种成分人参皂苷Rg1、人参皂苷Re、人参皂苷Rf、人参皂苷Rb,、人参皂苷Rb2、人参皂苷Rb3、黄芪甲苷分别在0.2028~2.028μg(r=1.00),0.3788~3.788μg(r=1.00),1.6862~16.862μg(r=1.00),0.8434—8.434μg(r=1.00),0.2048—2.048μg(r=1.00),0.1816。1.816txg(r=1.00)和0.1166—1.166μg(r=1.00)范围内呈良好的线性关系,平均回收率分别为98.1%(RSD为1.1%),98.1%(RSD为0.87%),98.5%(RSD为0.58%),98.2%(RSD为0.58%),98.6%(RSD为0.49%),98.7%(RSD为1.1%),98.5%(RSD为0.42%)。结论该方法多种成分同时测定,操作简便、准确、重复性好,可用于心脑舒口服液的质量控制。
AIM To develop a method for determining seven kinds of saponins in Xinnaoshu Oral Liquid (Astragali Radix, Ginseng Radix et Rhizoma, Schisandrae Chinensis Fructus, Codonopsis Radix, Ophiopogonis Radix). METHODS The quantative analysis was carried out on a column of Kromasil Cls by HPLC-ELSD, using a mobile phase of acetonitrile-water under a flow rate of 1 mL/min. RESULTS The linear ranges of ginsenoside Rgl, ginsenoside Re, ginsenoside Rf, ginsenoside Rbl, ginsenoside Rb2, ginsenoside Rb3 and astragaloside fell within the ranges of 0. 202 8-2. 028 μg, 0. 378 8-3.788 μg, 1. 686 2-16. 862 μg, 0. 843 4-8.434μg, 0. 204 8- 2. 048μg, 0. 181 6-1. 816μg, 0. 116 6-1. 166 μg, respectively, The seven components showed good linear corre- lations (r=1.00, r=1.00, r=1.00, r=1.00, r=1.00, r=1.00, r=1. 00). The recoveries were 98.1% for ginsenoside Rg1 , 98. 1% for ginsenoside Re, 98.5% for ginsenoside Rf, 98.2% for ginsenoside Rb1 , 98.6% for ginsenoside Rb2, 98.7% for ginsenoside Rb3, and 98.5% for astragaloside, respectively. The relative standard deviations were 1.1% , 0. 87% , 0.58% , 0. 58% , 0.49% , 1.1% , 0.42% , respectively (n =6). CONCLU- SION This method is simple, accurate, reproducible and convenient for the quality control over Xinnaoshu Oral Liquid.
