OBJECTIVE
To determine the total content of astragaloside IV in Radix Astragali.
METHODS
The measurement conditions were used as follows: Irregular C18 (4.6 mm x 250 mm, 5 microm) column; mobile phase: acetonitrile-water (32:68); flow rate: 1.0 ml/min; detector: ELSD 2000; the temperature of drift tube: 100 degrees C; gas flow: 2.7 L/min.
RESULTS
Eight batches of Radix Astragali from different sources were determined. The stability, precision and reproducibility of the method were studied, RSD <3%.
CONCLUSION
There is great difference between the content of astragaloside IV in Radix Astragali by different processing methods.
目的
测定黄芪中黄芪甲苷的总含量。
方法
采用以下测定条件：不规则C18柱（4.6 mm×250 mm，5微米）；流动相：乙腈-水（32:68）；流速：1.0 ml/分钟；检测器：ELSD 2000；漂移管温度：100℃；气体流速：2.7 L/分钟。
结果
测定了8批不同来源的黄芪。研究了该方法的稳定性、精密度和重现性，相对标准偏差<3%。
结论
不同加工方法的黄芪中黄芪甲苷的含量存在很大差异。
