Characterization of chemical constituents in Rhodiola Crenulate by high‐performance liquid chromatography coupled with Fourier‐transform ion cyclotron resonance mass spectrometer (HPLC‐FT‐ICR MS)

In this work, an approach using high-performance liquid chromatography coupled with diode-array detection and Fourier-transform ion cyclotron resonance mass spectrometer (HPLC-FT-ICR MS) for the identification and profiling of chemical constituents in Rhodiola crenulata was developed for the first time. The chromatographic separation was achieved on an Inertsil ODS-3 column (150 mm × 4.6 mm,3 µm) using a gradient elution program, and the...
