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 detection was performed on a Bruker Solarix 7.0 T mass spectrometer equipped with electrospray ionization source in both positive and negative modes. Under the optimized conditions, a total of 48 chemical compounds, including 26 alcohols and their glycosides, 12 flavonoids and their glycosides, 5 flavanols and gallic acid derivatives, 4 organic acids and 1 cyanogenic glycoside were identified or tentatively characterized. The results indicated that the developed HPLC‐FT‐ICR MS method with ultra‐high sensitivity and resolution is suitable for identifying and characterizing the chemical constituents in R. crenulata . And it provides a helpful chemical basis for further research on R. crenulata . Copyright © 2016 John Wiley & Sons, Ltd.
