From the roots of Acmella decumbens (Sm) R.K.Jansen three compounds belonging to the alkamide family were isolated: (2E,4E)-N-hydroxiphenylethyl-2,4-decadien-9- inamide (1); (4E,6E)-N-isobutyl-4,6-undecen-10-inamide (2); and (2Z)-N-phenylethyl-2- nonane-6,8-diinamide (3). The structures were determined by means of IR, MS, 1H NMR, 13C NMR, DEPT 135and COSY. Compounds 1 and 2 are reported for the first time while 3 was previously isolated from Spilanthes acmella L.DEPT 135and COSY. Compounds 1 and 2 are reported for the first time while 3 was previously isolated from Spilanthes acmella L. DEPT 135and COSY. Compounds 1 and 2 are reported for the first time while 3 was previously isolated from Spilanthes acmella L.
