7,9′-Epoxylignan and other constituents of Zanthoxylum culantrillo

Methylpiperitol, sitosterol, skimmianine, afzelin and quercitrin were isolated from the leaves of Zanthoxylum culantrillo (Rutaceae), while the stem bark yielded (+)-methylpiperitol, sitosterol, lupeol, (+)-sesamin and the new tetrahydrofuran lignan 3,4-dimethoxy-3′,4′-methylenedioxy-7,9′-epoxyligna...

Description
Summary:Methylpiperitol, sitosterol, skimmianine, afzelin and quercitrin were isolated from the leaves of Zanthoxylum culantrillo (Rutaceae), while the stem bark yielded (+)-methylpiperitol, sitosterol, lupeol, (+)-sesamin and the new tetrahydrofuran lignan 3,4-dimethoxy-3′,4′-methylenedioxy-7,9′-epoxylignan-9-ol, 1a. Methylpiperitol, sitosterol, skimmianine, afzelin and quercitrin were isolated from the leaves of Zanthoxylum culantrillo, while the stem bark yielded (+)-methylpiperitol, sitosterol, lupeol, (+)-sesamin and the new tetrahydrofuran lignan 3,4-dimethoxy-3′,4′-methylenedioxy-7,9′-epoxylignan-9-ol. Their structures were elucidated by NMR, including 2D techniques and comparison with authentic samples.
