Simultaneous Determination of Five Components in Uyghur Drug and by UPLC[J]. Chinese journal of experimental traditional medical formulae, 2014, 20(17): 65-68. DOI: 10.13422/j.cnki.syfjx.2014170065.
Objective: This study was conduct to establish an UPLC method for the simultaneous determination of five components aesculin
esculetin
lactucin
cichoric acid and lactucopicrin in Uyghur drug Cichorium glandulosum and C. intybus. Method: Hypersil BDS C18 (4.6 mm×250 mm
5 μm) was used as the stationary phase. The mobile phase was composed of acetonitrile and 0.4% phosphoric acid aqueous with a gradient elution. The flow rate was 1.0 mL·min-1. Column temperature was 30 ℃. The detection wavelength was 254 nm. Result: All calibration curves showed good linear regression (r>0.999 3) within test ranges. The validation data indicated excellent precision and good recovery. Conclusion: The method was successfully applied to quantify five components in C. glandulosum and C. intybus
which could be used as comprehensive quality evaluation of Cichorium.
