| Popis: | Remiria maritime Aubl., popularly known as "capim da praia" is used as teas to treat diarrhea, kidney disease, high fever and analgesic and antiinflammatory. There are no records in the literature about its biological properties. Therefore, this study was designed to evaluate the possible action of the antimicrobial effects, antioxidant, antinociceptive and antiinflammatory effect of aqueous extract of dried sea Remiria Aubl. (ERMA) using tests in vivo and in vitro. The extract was first subjected to tests phytochemicals. Antimicrobial activity was evaluated in vitro by the technique of disk diffusion method and minimum inhibitory concentration. The antioxidant effect was observed in vitro by testing the extent of lipid peroxidation (TBARS), nitric oxide (NO) and hydroxyl radical scavenger capacity where ERMA concentrations used were 10 μg/mL, 100 μg/mL e 1 mg/mL. The antinociceptive activity was evaluated by testing the writhing induced by acetic acid 0.9% and 1% formalin. The test of motor coordination was used to assess possible effects of muscle relaxants and sedatives ERMA might interfere with the antinociceptive effects. The anti-inflammatory activity was evaluated by testing peritonitis induced by carrageenan 1%. The animals (n = 6/group) were treated 30 min before each experiment, vehicle (saline + 0.2% Tween 80, ip) or ERMA (100, 200 and 400 mg / kg, ip). The phytochemical screening showed the presence of several chemical classes: phenols, tannins, alkaloids, volatile coumarins, flavonoids, saponins and triterpenes. The ERMA demonstrated antimicrobial activity against Gram-positive and negative. Additionally, evaluation of antioxidant activity in the TBARS assay, there was a reduction of lipid peroxidation (p |
