A New Lignan from the Leaves of Zanthoxylum armatum

Abstract

A new furofuran lignan, zanthonin (1) together with 13 known compounds including seven furofuran lignans (2–8), one isobutyl amide (9), a furanocoumarin (10) and four flavonoids (11–14) have been isolated from the leaves of Zanthoxylum armatum. The chemical structures of these compounds were elucidated mainly on the basis of NMR (1D and 2D) and MS data. This is the first report on the isolation of methylxanthoxylol (4) from Z. armatum.
