“…Citral, another major component of EOCL, increased barbituric sleeping time of mice (Vale et al, 2002) and blocks the excitability of rat sciatic nerves (Sousa et al, 2015). Citral is also the main component of other EOs that have anesthetic effects in fish: Aloysia triphylla (Gressler et al, 2012;Parodi et al, 2014;Santos et al, 2017 Cymbopogon flexuosus (Limma-Neto et al, 2016) and L. alba citral chemotype (Souza et al, 2017). The anesthetic effects of citral in fish does not involve the benzodiazepine site of the GABAergic system γ-terpinene, also a major component of EOCL, increases dopamine release from rat brain striatum slices (Fukumoto et al, 2006), but to our knowledge, no study so far has analyzed the sedative and/or anesthetic activities of this compound.…”

This study investigated the anesthetic effect of the essential oils (EOs) from the peel of Citrus x aurantium (EOCA) and Citrus x latifolia (EOCL) on silver catfish Rhamdia quelen. Fish were exposed to different concentrations of EOCA and EOCL to determine time of anesthesia induction and recovery. Induction of anesthesia was observed in all fish exposed to 400, 600 or 800 μL L−1 EOCA and 300, 400 or 500 μL L−1 EOCL. Another group of fish were exposed for 8 h to 50, 100, or 200 μL L−1 of either EOs. Overall, fish exposed to ethanol and both EOs presented higher ventilatory frequencies (VF) than the control group throughout the 8 h of exposure. Net ion (Na+, K+ and Cl−) effluxes and ammonia excretion were significantly lower in fish exposed to 50, 100 or 200 μL L−1 of either EOs compared to control fish. Mortality was 37% in fish exposed to 200 μL L−1 of either EOs after 8 h. These findings suggest that EOCA and EOCL are useful anesthetics and sedatives for Rhamdia quelen, but their usefulness as alternatives to reduce stress in fish transportation at the lower concentrations tested (50-100 µL L−1) deserves further study.

“…The water parameters were kept in the following ranges: pH 7.5, conductivity 500 µS, ammonium concentration < 0.004 ppm, and temperature 26 ± 1 • C. For the behavior studies, acclimated zebrafish were randomly assigned into the control, the scopolamine (Sco, 100 µM, Sigma-Aldrich, Darmstadt, Germany), and three REO treatment groups (25,150, and 300 µL/L). The doses of the essential oil were chosen with reference to previous reports [24]. REO (25,150, and 300 µL/L) was administered individually by immersion to zebrafish (Danio rerio) through transferring into 500 mL glass for 1 h, once daily for eight days, whereas scopolamine (100 µM) treatment was delivered individually by transferring into a 500 mL glass, 30 min before behavioral tests.…”

Rosmarinus officinalis Essential Oil Improves Scopolamine-Induced Neurobehavioral Changes via Restoration of Cholinergic Function and Brain Antioxidant Status in Zebrafish (Danio rerio)

Rosmarinus officinalis L. is a traditional herb with various therapeutic applications such as antibacterial, antioxidant, anti-inflammatory, antidepressant, and anticholinesterase activities, and can be used for the prevention or treatment of dementia. In the present study, we tested whether Rosmarinus officinalis L. could counteract scopolamine-induced anxiety, dementia, and brain oxidative stress in the zebrafish model and tried to find the underlying mechanism. Rosmarinus officinalis L. essential oil (REO: 25, 150, and 300 µL/L) was administered by immersion to zebrafish (Danio rerio) once daily for eight days while scopolamine (100 µM) treatment was delivered 30 min before behavioral tests. The antidepressant and cognitive-enhancing actions of the essential oil in the scopolamine zebrafish model was measured in the novel tank diving test (NTT) and Y-maze test. The chemical composition was identified by Gas chromatograph–Mass spectrometry (GC-MS) analysis. The brain oxidative status and acetylcholinesterase (AChE) activity was also determined. REO reversed scopolamine-induced anxiety, memory impairment, and brain oxidative stress. In addition, a reduced brain AChE activity following the administration of REO in scopolamine-treated fish was observed. In conclusion, REO exerted antidepressant-like effect and cognitive-enhancing action and was able to abolish AChE alteration and brain oxidative stress induced by scopolamine.

“…In the present study, the main components of CcEO were geranial (44.74 %), neral (31.00 %), geraniol (8.08 %) and geranyl acetate (5.98 %) (Table 1). A. triphylla and C. flexuosus essential oils with high α-citral (geranial) and β-citral (neral) contents induced deep anesthesia in Rhamdia quelen (Santos et al 2017). These results showed that the citral components have anesthetic properties in fish species.…”

“…Many studies have been carried out on various herbal essential oils as anesthetic agents such as Lippia alba, Hesperozygis ringens, Lippia sidoides, Ocotea acutifolia, Cinnamomum camphora, Mentha arvensis, Aloysia triphylla, Cymbopogon flexuosus, Matricaria chamomilla, Origanum sp., Eucalyptus sp., Melaleuca alternifolia, Pelargonium graveolens and Aniba rosaedora (Cunha et al, 2010;Silva et al, 2013;Pedrazzani and Neto, 2016;Santos et al, 2017;Can et al, 2017;Bodur et al, 2018;Correia et al, 2018;Can et al, 2018;Kizak et al, 2018).…”
