Natural products are gaining much importance in light of the serious side effects posed by drugs of chemical origin. High intake of foods rich in antioxidants reduces the risk of neurodegenerative disorders. Traditionally, Allium sativum L.(garlic) and Allium cepa. L (onion) has received considerable attention for their therapeutic benefits around the globe. The present study assesses the free radical scavenging role of Allium sativum and Allium cepa in cerebral cortex, striatum, and hippocampus. Adult wistar rats of either sex were grouped as control group (Group I) treated with normal saline and the two experimental group were treated with the aqueous bulbous extracts of dehydrated Allium sativum (Group II) and Allium cepa (Group III) was considered as treated groups. Homogenates of hippocampus, striatum and cerebral cortex were analyzed for biochemical and neuronal analysis. LD50 value of these extracts in rats was found at a dose of 500 mg/kg BW. A Significant decline (P<0.05) in the MDA level was observed in the hippocampus, striatum and cerebral cortex in group II when compared to group III. Total antioxidant level, GSH, SOD level was significantly high (P<0.001) in the treated groups. Neuronal increase was significant in Group II (P < 0.01) when compared to Group III. Allium sativum and Allium cepa was found to have a challenging role in hampering oxidative stress in Hippocampus, striatum and cerebral cortex, the target regions in neurological disorders. However, ample number of studies are required to establish their mechanism of action as a progression to clinical approach.
