【Abstract】 Objective To establish a HPLC-ELSD method to determination of astragaloside Ⅳ in Buzhongyiqi Wan.Methods Diamonsil-C18 column(200 mm× 4.6 mm,5 μ m) was employed,and its temperature was 30 ℃.Axetonitrile-water(38:62) was as the mobile phase at the flow rate of 0.8 mL/min.ELSD inlet heater was set at 110 ℃,and N2 flow rate of 3.0 L/min.Results The calibration curve of astragaloside Ⅳ was linear in the range of 2.494-39.904 μg(r=0.999 9).The average recovery was 97.26%,RSD=1.94%(n=6).Conclusion The... 更多还原 【关键词】 高效液相色谱-蒸发光散射法; 补中益气丸; 黄芪甲苷; 含量测定; 【Key words】 HPLC-ELSD; Buzhongyiqi Wan; astragaloside Ⅳ; content determination;
