Reactive oxygen species (ROS) play an important role in ageing and age-related neurodegenerative changes including Parkinson’s disease (PD). PD is characterized by signs of major oxidative stress and mitochondrial damage in the pars compacta of the substantia nigra. Present study was designed to investigate whether the Centella asiatica extract (CAE) would prevent 1-methyl-4-phenyl-1,2,3,6 - tetrahydropyridine (MPTP) - induced neurotoxicity in aged Sprague-Dawley rats. Adult, male Sprague-dawley rats of 300-350 g were divided into control, C. asiatica alone, MPTP alone (20 mg/kg, for 21 days) and MPTP with C. asiatica (300 mg/kg for 21 days) groups. Effect of aqueous extract of C. asiatica on oxidative biomarker levels in corpus striatum and hippocampus homogenate was examined. MPTP-challenged rats elicited a significant increase in lipid hydroperoxides (LPO) (p < 0.01), protein-carbonyl-content (PCC) (p < 0.01) and xanthine oxidase (XO) (p < 0.01) when compared with control rats. There was a significant decrease in total antioxidants (TA) (p < 0.001), superoxide dismutase (SOD) (p < 0.001), glutathione peroxidase (GPx) (p < 0.01) and catalase (CAT) (p < 0.001) levels with MPTP treatment. Supplementation of CAE reduced LPO and PCC and significantly increased (p < 0.01) TA and antioxidant enzyme levels (p < 0.01) in corpus striatum and hippocampus. These results show that administration of C. asiatica was effective in protecting the brain against neurodegenerative disorders such as Parkinsonism.
