A rare hetero dimeric terpenoid derivative, named japonicaside C, together with five known secoiridoid gloucosides were isolated from the flower buds of Lonicera japonica. The structures of these compounds were established on the basis of spectroscopic analyses. Japonicaside C is the first representative of a novel type of hetero dimeric terpenoid, biogenetically originated from a guaiane-type sesquiterpenoid and a secoiridoid glucoside. Anti-virus activity of the isolated compounds was evaluated in vitro.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
