Abstract A new dibenzo- p -dioxin biphenyl bisbenzylisoquinoline alkaloid, pachyovatamine, has been isolated from an extract of the leaves and stems of Pachygoneovatafrom Sri Lanka. The alkaloid was characterized by a consideration of its physicochemical data and conversion to O -acetyltiliacorinine. Pachygonamine, N -methylpachygonamine and tiliamosine were also isolated from the same extract.
Abstract The leaves of Tiliacoraracemosa yielded N -methyltiliamosine, a new diphenylbisbenzylisoquinoline alkaloid whose constitution was established from spectral as well as synthetic methods.
