Abstract： Objective： To conduct a qualitative analysis of the chemical components in desert wines from Wuhai city using ultra-high performance liquid chromatographycoupled with quadrupole time-of-flight mass spectrometry.Method： A Waters ACQUTY UPLC HSS T3 column （ （100mm×2.1 mm， 1.8μm ）was used. The mobile phase was 0.1% formic acid aqueous solution-acetonitrile （gradient elution），with a flow rate of 0.3mL?min-1 ， a column temperature of 40°C ，and an injection volume of 3μL . An electrospray ionization source was employed， and data were collected in both positive and negative ion modes.Result： Atotalof114 chemical components were identified in the desert winesfrom Wuhai city.These compounds mainly included20 amino acids， 33 organic acids，24 flavonoids， etc.

Keywords： Wuhai desert wine; ultra-high performance liquid chromatography coupled with quadrupole time of-flight mass spectrometry; chemical constituents; structural identification
