- W2365844777 abstract "Objective: To establish an optimal RPHPLC method to determine the contents of caffeic acid and protocaechuic aldehyde from Leontopodium leontopodioides(Wild.)Beauv.Method:Column:Alltech alltima C__(18)(4.6mm×250mm,5μm),mobile phase:methanol—0.05%phosphoric acid(25∶75),column temperature:25℃,flow rate:1.0 ml·min~~(-1),wavelength:280nm before 13 minutes and 323 nm afterwards.Results:The calibration curve of caffeic acid and protocaechuic aldehyde were linear respectively over the range of 0.0822～0.822μg,and 0.01498～0.1498μg.The corresponding mean recovery rate were 99.40%with RSD 1.23%(n=6)and 97.96%with RSD 1.42%(n=6)accordingly.Conclusion:The HPLC method established was simple,feasible,accurate,highly sensitive and reliable,which can be used to control the quality of Leontopodium 1eontopodioides(Wild.)Beauv." @default.
