A previous undescribed dihydrobenzofuran neolignan (1), as well as eleven known phenolic derivatives (2–12) were isolated from the n-butanol fraction of the roots of Actinidia valvata Dunn, including five phenylpropanoids (2–6), four phenolic glycosides (7–10) and two coumarins (11–12). The chemical structures of these compounds were identified by means of extensive spectroscopic analysis and comparison with the previously reported data. Besides, the chemotaxonomic significance of these secondary metabolites was discussed.
