Abstract:Two new alkamides, 8,11-dihydroxy-dodeca-2E,4E,9E-triensaureisobutylamid (Compound 1) and 7-hydroxy-trideca-2E,8E-dien-10,12-diynoic acid isobutylamide (Compound 2), as well as eight known compounds were isolated from the whole plants of Spilanthes callimorpha. The structures of the alkamides were characterized on the basis of their spectral data.
