A simple amide, N-2-phenylethylcinnamamide and three known compounds, stigmasterol and taraxasteryl and lupeyl acetates, were isolated from the leaves of Spilanthes ocymifolia The structure of the cinnamamide derivative was established by spectroscopic means and confirmed by synthesis; From the red alga Laurencta ndtjica a new sesqulterpene of cyclolaurane-type was isolated, and the structure elutidated by spectra1 analyses and chemical means
