New alkylamides from pericarps of Zanthoxylum bungeanum

Two new unsaturated alkylamides (2E,7E,9E)-N-(2-hydroxy-2-methylpropyl)-6,11-dioxo-2,7,9-dodecatrienamide (1) and (2E,6E,8E)-N-(2-hydroxy-2-methylpropyl)-10-oxo-2,6,8-decatrienamide (2) together with six known compounds (3–8) have been isolated from the pericarps of Zanthoxylum bungeanum. Their structures were elucidated on the basis of extensive spectroscopic analysis, including MS, IR, 1D and 2D NMR experiments.
