Abstract: Sea buckthorn fruit oil was obtained by supercritical CO2 extraction, and its flavonoid components were analyzed by ultra-high performance liquid chromatography-mass spectrometry (UPLC-MS) through Peakview workstation matching followed by tandem mass spectrometric analysis and comparison of ultraviolet spectroscopic data and mass spectral data with those of reference standards as well as with literature data. A total of 18 flavonoid compounds were determined, including eight flavonol aglycones and flavonol glycosides, three dihydroflavonol aglycones and dihydroflavonol glycosides, five flavonoid aglycones and flavonoid glycosides, one dihydroflavonoid aglycon and one flavanol glycoside. To our knowledge, apigenin-6-C-glucoside-8-C-xyloside, catechin-7-glucopyranoside, alizarin, violet and locustin were found in sea buckthorn for the first time.
