Objective: To establish a method for determination of imperatorin and isoimperatorin in Angelicae Dahurica by UPLC. Method: The content of Imperatorin and isoimperatorin was determined with UPLC in this preparation. The Thermo Hypersil GOLD C18(2.1 mm×100 mm
1.9 μm) column was used. The mobile phase consisted of methanol-water (55∶45)solution. The flow rate was 0.2 mL·min-1 and column temperature was at 30 ℃. The detecting wave length was at 300 nm Result: The two components had a good linearity relationship between 7.8-70.2 ng;5.04-45.36 ng.The average recoveries(n=6) were 98.82%(RSD 1.25)
100.14%(RSD 1.16). Conclusion: The methods is simple
accurate
rapid and reproducible
it can be used as an effectively method for the determination of imperatorin and isoimperatorin in Angelicae Dahurica.
