Two new members of capsaicinoids N-(4-hydroxy-3-methoxybenzyl)-8-methylnon-trans-4- enamide and N-(4-hydroxy-3-methoxybenzyl)-3,7-dimethyloct-6-enamide were synthesized, and their structures were confirmed by elemental analysis, FT-IR, 1H NMR, 13C NMR etc. Meanwhile, their pungencies were determined through scoville organoleptic test and compared with capsaicin, norcapsaicin and homocapsicin. The double bond location, branch chain and length of the alcyl chain were confirmed to be the structural factors that could affect the pungency re-markably.

Key words: capsaicinoid, synthesis, pungency factor
