Abstract: D-004, a lipid extract of Roystonea regia fruits that contains oleic, lauric and myristic acids as major components inhibits α1-adrenoreceptors-mediated contractile responses in isolated rat vas deferens and prostate trips; no study has demonstrated a similar effect for oleic, lauric or myristic acids individually. Therefore, the effects of D-004 (250 g/ml), oleic (100 g/ml), lauric (50 g/ml) or myristic (25 g/mL) acids and their combined effects on phenylephrine (PHE: 10-7- 10-4 mol/L) induced contractions has been studied. No treatment changed the basal tone of the preparations, but all inhibited PHE-induced contractions. D-004 produced the highest inhibition, followed by lauric acid, which was more effective than myristic and oleic acids against PHE-induced contractions of control group. D-004 and the mixture of the three acids produced similar inhibitions
