Examination of the amide constituents in Budo-Zanthoxylum fruit, the most traded commercial Zanthoxylum fruit in the Japanese market, has led to the isolation of a new amide, along with α-, β-, γ-, hydroxy-α-, hydroxy-β- and hydroxy-γ-sanshools. The structure of the new amide was assigned as (2E, 4E, 8E, 10E, 12E)-N-isobutyl-2,4,8,10,12-tetradecapentaenamide by spectral examination
