Objective: To establish a new RP-HPLC method for simultaneous determination of calycosin
atractylenolide-1
atractylenolide Ⅲ in crude extract of Radix astragali-Atractylodis Macrocephalae herb couple.Method: Analysis was carried out on a Kromasil 100-5C18(4.6 mm×250 mm) column with acetonitrile-pure water as mobile phases in gradient elution.The flow rate was 1 mL·min-1
and the UV detector was monitored at 220 nm.Result:All calibration curve showed good linear regression in test ranges(r>0.999 5);and the overall recoveries were in the range of 97%-103%(n=3)with RSD less than 3%.The overall RSD of precision test was less than 3%.Conclusion: The method is rapid
acute
credible and repeatable
and can provide bases for the material basis and compatibility for Radix astragali-Atractylodis Macrocephalae herb couple.
