Diterpenes and lignans from Viburnum odoratissimum var. odoratissimum

Abstract

A new diterpenoid, dehydrovibsanin G (1), a new lignan, (+)-9′-O-senecioyllariciresinol (2), and six known compounds (3–8) were isolated from the branches and leaves of Viburnum odoratissimum var. odoratissimum. The structures of these compounds were elucidated by analysis of spectroscopic data. Both new compounds showed moderate inhibitory activity against human A431 and T47D tumor cell lines.
