Extracts of four species of seaweeds, Ulva lactuca L. (green), Liagora farinosa Lamouroux (red), Padina pavonia L. and Turbinaria ornata Turn (brown), were screened for their antimicrobial, and antimalarial activities, and binding affinity for human opioid receptors. Phytochemical analysis led to the isolation and identification of 10 constituents: fucosterol, stearic acid, palmitic acid, palmitoleic acid, oleic acid, myristic acid, p-hydroxybenzoic acid, β-sitosterol, glycerol-1-olyl-3-palmotyl-2-galactoside, and glycerol-1,3-diolyl, The last two compounds displayed strong binding affinity to delta opioid receptors.
