Abstract

Abstract: Sixteen compounds, including six flavonoids (1 –6 ), one lignan (7 ), three megastigmanes (8 –10 ), three triterpenoids (11 –13 ), and three benzoic acid derivatives (14 –16 ) were isolated and structurally elucidated from the pseudo-fruits of Hovenia dulcis . Their structures were analyzed by NMR spectroscopic and data comparison. Among them, compounds 4, 7 –11, 13, 15, and 16 were isolated from the Hovenia genus for the first time. The chemotaxonomic significance of the isolates was also described, which revealed a relationship between H. dulcis and H. acerbar as well as other species belonging to the Rhamnaceae family.
