The present study investigated the phytochemical constituents of Semiliquidambar chingii for the first time, resulting in the isolation and characterization of nineteen compounds which were categorized into eight groups as resveratrol derivatives (1–4), triterpenoids (5–10), flavonoids (11–13), phenolic glycosides (14–15), lignan (16), ellagic acid derivative (17), coniferyl alcohol derivative (18), and shikimic acid derivative (19). The chemical structures of these compounds were elucidated based on the careful analysis of spectroscopic data and comparison with reported data. This is the first report of isolation of compounds 1–19 from S. chingii and compounds 1–4, 5–7, 9–11, and 14–19 within the genus Semiliquidambar. Furthermore, the chemotaxonomic significance of the isolates was discussed in detail, which might provide important chemical taxonomic evidence supporting the hybrid origin of Semiliquidambar from the genera Altingia and Liquidambar.
