We examined the sedative, anxiolytic and antidepressant effects of essential oil (EO) of leaves from Citrus limon, which has been used as one of the most popular compounds in Brazilian traditional herbal medicine. The effects of EO were demonstrated by open-field, elevated-plus-maze, rota rod, pentobarbital-induced sleeping time, and forced swimming tests(More)
Studies showing anxiolytic-like properties of natural products have grown. This paper evaluated if carvacryl acetate (CA) could be studied as an alternative drug to treat anxiety disorders. Elevated plus maze (EPM) tests , light-dark box (LDB) tests, and marble-burying tests (MBTs) were performed on mice. In the first protocol, the anxiolytic-like(More)
Blood flukes of the genus Schistosoma are the causative agents of human schistosomiasis, a debilitating disease that afflicts over 200 million people worldwide. Praziquantel is the drug of choice but concerns over praziquantel resistance have renewed interest in the search for alternative drug therapies. Carvacrol, a naturally occurring monoterpene phenol(More)
The aim of this study was to evaluate the neuroprotective effects of nerolidol in mice hippocampus against oxidative stress in neuronal cells compared to ascorbic acid (positive control) as well as evaluated the nerolidol sedative effects by open field test compared to diazepam (positive control). Thirty minutes prior to behavioral observation on open field(More)
The objective of the present study was to evaluate the antinociceptive effects of phytol using chemical and thermal models of nociception in mice and to assess its antioxidant effects in vitro. Phytol was administered intraperitoneally (i.p.) to mice at doses of 25, 50, 100, and 200 mg/kg. In the acetic acid-induced writhing test, phytol significantly(More)
The present study evaluated anxiolytic activity of (+)-limonene epoxide (EL), through the marble burying test (MBT) assay, and the antioxidant potential in vitro and in vivo in mice hippocampus of adult mice subjected to experimental anxiety protocol. For behavioral studies, and in vivo antioxidant analyses, mice were treated orally with 0.05% Tween 80(More)
The essential oil of Myrtus communis L. (Myrtaceae) and its compounds have been popularly used in numerous health disorders, including insomnia and nervous conditions, but their effects on central nervous system (CNS) have not been explored yet. We evaluated the anxiolytic-like effects and possible action mechanism of (-)-myrtenol (MYR), a monoterpenoid(More)
The antioxidant and antinociceptive activities of Citrus limon essential oil (EO) were assessed in mice or in vitro tests. EO possesses a strong antioxidant potential according to the scavenging assays. Moreover, it presented scavenger activity against all in vitro tests. Orally, EO (50, 100, and 150  mg/kg) significantly reduced the number of writhes, and,(More)
Epileptic syndromes are highly prevalent neurological conditions and can often be disabling. In order to find an alternative for treatment, this study evaluated anticonvulsant effects of carvacryl acetate (CA), a derivative of monoterpene carvacrol, after seizures induced by pilocarpine (P400), picrotoxin (PIC) or pentylenetetrazol (PTZ). We also analyzed(More)
This study investigated in vitro and in vivo antioxidant potential of carvacryl acetate (CA), a derivative of carvacrol, monoterpenic component of oregano. The correlation between in vitro and in vivo CA effects was also determined. In vitro tests measured thiobarbituric acid reactive species content, nitrite formation and hydroxyl radical levels. In vivo(More)
