摘要: |
本文建立了HPLC-ELSD法测定黄芪多糖注射液中黄芪甲苷的含量。采用Agilent Ecplise XDB-C18柱(250mm×4.6mm,5µm);流动相:乙腈—水(35:65);流速1.0ml/min;柱温30℃;蒸发光散射(ELSD)检测器;漂移管温度:105℃;气体流速:2.70L.min-1,进样量20µL。结果表明:黄芪甲苷在10~400µg.mL-1范围内线性关系良好(R2=0.9998),平均加样回收率(n=3)为98.9%~99.6%,RSD为0.8%~1.8%。结果表明本法简便,快速,准确,重现性好,可用于控制该制剂的质量。 |

Abstract: |
A high performance Liquid chromatographic- ELSD method was reported for quantitative determination of AstragalosideⅣ with Agilent Ecplise XDB-C18 Column(250mm×4.6mm,5µm), mobile phsae acetomical—water(35:65); flow rate was 1.0ml/min; column temperature was 30℃;.The temperature of drift tube for measurement was 105℃ and the flow rate of N2 was 2.70L.min-1.On these conditions, the linear ranges were 10~400µg.mL-1(R2=0.9998)The average recovery was 98.9%~99.6% . The method was sensitive , reliable, accurete and repeatability, it can be used for quality control method of Astragalus Polysaccharide injection. |
