摘要 目的:建立复方扶芳藤胶囊(红参,黄芪、扶芳藤等)中卫矛醇和黄芪甲苷的含量测定方法。方法:采用正相HPLC法,色谱柱:Lichrospher5-NH2柱(250mm×4.6mm,5μm);流动相:乙腈-水(91∶9);流速1.0mL/min;柱温为28℃;检测器:PL-ELS2100型蒸发光散射检测器(漂移管温度:65℃,雾化室温度:50℃,气体流量:0.9L/min)。结果:卫矛醇进样量在2.91~29.1μg范围内,黄芪甲苷在1.03~10.3μg范围内,其峰面积的自然对数(Y)与进样量的自然对数(X)呈良好的线性关系(r>0.9990),卫矛醇和黄芪甲苷的平均加样回收率分别是99.24%和103.17%,RSD分别为2.6%和1.8%(n=6)。结论:该方法稳定、重复性好,结果准确,可作为复方扶芳藤胶囊中卫矛醇和黄芪甲苷的含量测定方法。 AIM: To establish an HPLC-ELSD method for determing dulcitol and astragaloside in Compound Fufangteng Capsules (Radix et Rhizoma Ginseng rubra, Radix Astragali, Herba Euonymi, etc). METHOD: Chromatographic conditions included Lichrospher 5-NH2 column (250 mm×4.6 mm, 5μm) and the mobile phase consisting of a mixture of acetonitrile-water (91:9). The flow rate of mobile phase was 1.0 mL/min. The column tempe-rature was at 28℃. Detector: PL-ELS2100 ELSD ( Eva : 65 ℃, Ned : 50 %, gas flow : 0.9 L/min). RESULTS: The linear ranges of dulcitol and astragaloside were 2.91 -29.1 μg (r = 0. 999 8 ) and 1.03 - 10.3μg ( r = 0. 999 1 ) , respectively. The average recoveries of dulcitol and astragaloside were 99.24% and 103.17% with corresponding RSD of 2.6 % and 1.8% ( n = 6) , respectively. CONCLUSION : The method is steady and with good repeatability, and can be used to determine the content of dulcitol and astragaloside in Compound Fufangteng Capsules.
