This work presents the behavioral effects of riparin I (methyl ether of N‐benzoyl tyramine) from unripe fruit of Aniba riparia (Lauraceae) on the elevated plus maze, open field, rota rod and hole board tests in mice. Riparin I was administered acutely by intraperitoneal (i.p.) and oral routes to male mice at doses of 25 and 50 mg/kg. The results showed that riparin I (25 and 50 mg/kg, i.p. and per os) increased the number of entries and the time of permanence in the open arms in the plus maze test. Similarly, in the hole board test, riparin I in both routes increased the number of head dips. Riparin I with both doses and routes had no effects on spontaneous motor activity in mice or in the rota rod test, but decreased the number of groomings. These results showed that riparin I by both administration routes has effects on the central nervous system with antianxiety effects on the plus maze and hole board tests. The substance is devoid of myorelaxant effects. Copyright © 2005 John Wiley & Sons, Ltd.
