A novel triterpenoid, cyclocarioside K, together with fifteen known compounds, including seven triterpenoids (2–8), five flavonoids (9–13), three phenolic derivatives (14–16), was obtained from the leaves of Cyclocarya paliurus (Batal.) Iljinsk (Juglandaceae). Their structures were elucidated by spectroscopic methods, including two-dimensional NMR experiments (HSQC DEPT and HMBC). The chemotaxonomic relationships were also discussed. As a result, 3, 4-secodammarane triterpenoids and kaempferol glycosides may represent phytochemical fingerprints for C. paliurus, and C. paliurus has close relationships with other species of Juglandaceae. •We studied the isolation of Cyclocarya paliurus and obtained sixteen compounds.•The structures of these compounds were elucidated by spectroscopic methods.•Cyclocarioside K was a new compound and five other compounds were firstly obtained from Cyclocarya genus.•C. paliurus has close relationship with some species of Juglandaceae family.
