Conditions
Selaginella delicatula aqueous extract demonstrates significant neuroprotective potential by treating rotenone-induced dopamine depletion. It effectively addresses oxidative stress by reversing the elevation in ROS levels caused by rotenone. The extract also restores normal physiological balance by treating the rotenone-induced elevation in hydroperoxides. Furthermore, it mitigates cellular damage by treating the rotenone-induced elevation in protein carbonyls. Finally, the plant extract manages antioxidant enzyme imbalances by treating the rotenone-induced elevation in the activities of glutathione-S-transferase.
Preparations
Selaginella delicatula is prepared as an aqueous extract to investigate its neuroprotective potential in biological models. This specific aqueous extract of Selaginella delicatula, referred to as SDAE, was utilized to enrich the diet of Drosophila melanogaster. Researchers applied this aqueous preparation to test its ability to mitigate oxidative stress and neurotoxicity induced by rotenone. By using the aqueous extract, the study was able to observe concentration-dependent protections against lethality and locomotor dysfunction. The preparation of Selaginella delicatula as an aqueous extract ultimately allowed for the successful restoration of antioxidant enzyme activities and mitochondrial integrity in the subjects.
