Determination of astragnaloside Ⅳ in zhuaikang capsule by HPLC-ELSD
Objective:To establish a method of determining the content of astragaloside IV in Zhuaikang Capsule.Method: The separation was performed on a Diamonsil C18(250 mm × 4.6 mm
5 μm) column with acetonitrile-water(33∶ 67) as the mobile phase.The flow rate was 1.0 mL.min-1.Temperature of drift tube was set at 105 ℃.The gas flow rate was at 2.7 L.min-1.Result:Astragaloside IV was linear in the range of 1.515 ~ 7.575 μg(r = 0.999 96).The average recovery rate of astragaloside IV was 98.83%
RSD 1.8%.Conclusion: This method is sensitive
accurate
and simple with little interference for the determination of astragaloside IV content.The method can be used for controlling the quality of Zhuaikang Capsule.
