Objective: To establish UPLC method for the determination of DAW22 from Ferula ferulaeoides of different growth periods in Xinjiang. Method: Solid phase extraction(SPE) was used for purification
and the determination was performed on ACQUITY UPLC BEH C18(2.1 mm×50 mm
1.7 μm) with methanol-1% formic acid solution as the mobile phase for gradient elution. The flow rate was 0.2 mL·min-1. Column temperature was 30℃ and UV detection wavelength was 316 nm. Result: The sample volume showed good linear relationship with area under the peak curve within the range of 6.21-124.2 ng(r=1.000 0) for DAW22. The average recovery was 99.81%
and the RSD was 2.0%. The content of DAW22 was highest for those grown in May 9th. Conclusion: This method is accurate
simple and reproducible
and can be applied to the quality control of F. ferulaeoides.
