合成了两种辣椒碱同系物的新成员: 反-N-(4-羟基-3-甲氧基苄基)-8-甲基-4-壬烯酰胺和N-(4-羟基-3-甲氧基苄基)-3,7-二甲基-6-辛烯酰胺, 并用元素分析, FT-IR, 1H NMR, 13C NMR等方法对其结构进行了表征, 还用斯科维尔感官评定的方法对其辣度进行了测定, 分别为1.2×107和3.0×106 SHU. 并将它们的结构和辣度与辣椒碱、降辣椒碱和高辣椒碱进行了对比, 总结出影响辣椒碱同系物辣度的结构因子为脂酰基双键的位置、脂酰基主链的长度及支链.

关键词: 辣椒素同系物, 合成, 辣度因子

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
