A main pungent amide, spilanthol (1), and three alkamides, (2E)-N-(2-methylbutyl)-2-undecene-8,10-diynamide (2), (2E,7Z)-N-isobutyl-2,7-tridecadiene-10,12-diynamide (3), and (7Z)-N-isobutyl-7-tridecene-10,12-diynamide (4) were isolated from the flower heads of Spilanthes acmella L. var. oleracea Clarke. Their structures were established by spectroscopic methods. Compounds 2 and 4 were new and 3 was found for the first time in Spilanthes species. Chemotaxonomic aspects are discussed.
从金纽扣（Spilanthes acmella L. var. oleracea Clarke）的头状花序中分离出一种主要的辛辣酰胺类化合物——毛叶花椒酰胺（1），以及三种链状酰胺类化合物：（2E）-N-（2-甲基丁基）-2-十一碳烯-8,10-二炔酰胺（2）、（2E,7Z）-N-异丁基-2,7-十三碳二烯-10,12-二炔酰胺（3）和（7Z）-N-异丁基-7-十三碳烯-10,12-二炔酰胺（4）。通过光谱方法确定了它们的结构。化合物2和4是新化合物，化合物3首次在金纽扣属植物中被发现。本文还讨论了化学分类学方面的问题。
