HighlightsDPIF of key substructures was applied to identify Acanthopanax TSs using MSAll and SWATH.Thirty‐three compounds were reported as potentially new compounds in genus Acanthopanax.A malonyl‐saponin was the first report in genus Acanthopanax. Abstract This paper focused on untargeted MSAll, also called MSE, and sequential window acquisition of all theoretical fragment‐ion spectra (SWATH) fragmentations for comprehensive structural characterization of triterpene saponins (TSs) in leaves of Acanthopanax senticosus through ultra‐high performance liquid chromatography electrospray quadrupole time‐of‐flight mass spectrometry (UPLC‐ESI‐QTOF). [M+H]+, [M + NH4]+ and [M + Na]+ precursor ions and the corresponding fragment ions were collected simultaneously in energy‐resolved MSAll. SWATH fragmentation was applied as a comparable and complementary method for resolving co‐eluting species. A workflow based on MSAll and SWATH fragmentations was constructed for comprehensive structural characterization and rapid discovery of TSs in leaves of A. senticosus. As a result, 89 TSs, along with 14 sapogenins, were unambiguously characterized or tentatively identified. Of these, 33 compounds were characterized as potentially new compounds, including the first report of malonyl‐saponin in genus Acanthopanax. This study aimed to systematically analyze TSs in leaves of A. senticosus, and the results are significant for the utilization of A. senticosus leaves.
