Introduction: The pathogenesis of Parkinson’s disease (PD) is multifactorial in which oxidative stress, neuroinflammation, and mitochondrial dysfunction are the leading factors. Currently, the antioxidant and anti-inflammatory agents of natural sources as neuroprotectants have raised much attention. The current study aimed to explore the neuroprotective effect of methanolic extract of Sargassum wightii in male Wistar albino rats against rotenone-induced PD. Methods: The rats were administered with rotenone (10 mg/kg orally) daily for 28 days to induce PD. S. wightii (200 mg/kg and 400 mg/kg) and levodopa+carbidopa combination (10 mg/kg) were administered to different groups of rats one hour prior to rotenone for 28 days. Behavioral parameters (akinesia, tremor, motor coordination, and locomotor activities) and body weight were recorded on days 14th and 28th of drug treatment. On the 28th day, the animals were sacrificed for the neurobiochemical analyses of brain tissue. Results: Rotenone treatment caused a significant reduction in behavioural parameters (P < 0.001), neurochemical deficits (P < 0.001), and elevation of oxidative stress markers (P < 0.001) in the brain. Pre-treatment with S. wightii at 200 mg/kg and 400 mg/kg doses significantly attenuated the rotenone-induced behavioral alterations and restored the mitochondrial NADH dehydrogenase activity and dopamine level in the striatum (P < 0.001). Moreover, 400 mg/kg of S. wightii restored the rotenone-induced increased oxidative stress markers like malondialdehyde (MDA), superoxide dismutase (SOD), and reduced glutathione (GSH) in the striatum (P < 0.01). Conclusion: S. wightii has provided a neuroprotective effect, probably by virtue of its antioxidant and dopamine restoring potential. Hence, it may offer a promising and new therapeutic lead for the treatment of PD but needs further research.

Objective: The study is aimed to evaluate the antiparkinsonian effect of polyherbal formulation containing methanolic extract of Prunus amygdalus, Arachis hypogaea, and Citrullus lanatus (MEPAC) in chlorpromazine (CPZ)-induced Parkinson’s disease in Wistar albino rats. Methods: The antiparkinsonian activity of polyherbal formulation was studied in CPZ (3 mg/kg i.p.) induced Parkinson rat model. Rats were subjected to treatment with MEPAC and standard drug for a period of 21 days. The behavioral assessments, i.e., catalepsy and locomotor activity were assessed during the treatment period. Then animals were sacrificed, brains were isolated and homogenized for the estimation of biochemical parameters such as dopamine (DA), lipid peroxidation (LPO), glutathione (GSH), and superoxide dismutase (SOD). Histopathology of the brains was also done. Results: The cataleptic score of MEPAC (200 mg/kg and 400 mg/kg) treated rats was significantly reduced. On the other hand, there was improved in the locomotor activity. MEPAC (200 mg/kg and 400 mg/kg) treated rats showed increase in the level of DA, reduced GSH, SOD, and decreased LPO significantly. Conclusion: It may be concluded that methanolic extract of polyherbal formulation consisting of P. amygdalus, A. hypogaea, and C. lanatus showed a good antioxidant and neuroprotective effect in CPZ-induced Parkinson rats.
