چکیده    Smilax aspera (liliaceae) has been used in herbal medicine for the treatment of many disorders. chemical analysis of this plant resulted in the isolation of the stilbene trans-resveratrol. the effects of this compound on rat isolated ileum and urinary bladder, blood pressure and inflammation, and nociception in mice have been examined. resveratrol (3x10-5 -1x10-1 mg/ml; or 1.3x10 7 - 4.4x10-4 m) caused a concentration-dependent relaxation in both ileal longitudinal segments and urinary bladder rings. intravenous doses of resveratrol (0.028- 8.5 mg/kg) caused a dose-dependent fall of systolic and diastolic blood pressure of anesthetized rats. oral administration of this compound (1.3, 4.0. 13 and 40 mg/kg) decreased carrageenan-induced paw edema in rats. furthermore, oral administration of resveratrol (3, 10, 30 and 100 mg/kg) decreased the number of writhes induced by i.p. injection of 0.8% acetic-acid in mice. these effects of resveratrol and its potential as a medicinal source were discussed in the light of the reported effects of resveratrol on nitric oxide and prostaglandin synthesis
