Abstract
Introduction: Oxidative stress plays a critical role in the pathological process of Alzheimer’s disease (AD). There is a growing interest in natural anti-oxidants and cholinesterase inhibitors from medicinal plants that may aid in the prevention of oxidative injury and treatment of AD. Considering this, Athamanta sicula L. is found to be an important medicinal plant.
Aims: The aim of the current study was to investigate the total phenolic content, antioxidant, and anticholinesterase properties of aqueous (AqE) and methanolic extracts (MethE) from Athamanta sicula L. (A. sicula L.).
Methods: The phenanthroline, ABTS free radical scavenging, and β-carotene bleaching methods were utilized to assess the antioxidant capacity. Acetylcholinesterase (AChE) and butyrylcholinesterase (BChE) inhibitory methods were used to determine the anti-cholinesterase effect.
Results: These extracts were found to be rich in phenolic contents. They were capable of scavenging free radicals, inhibiting lipid peroxidation, and reducing agents. A. sicula L. had a remarkable cholinesterase inhibitory effect.
Conclusion: These results support that A. sicula L. could be a new source of anti-oxidant and anticholinesterase natural drugs. Further studies on the isolation and characterization of active principles of anti-oxidant and tyrosinase inhibitory activities are needed.
Keywords: Athamanta sicula L., phenolic compounds, antioxidant potential, cholinesterase, inhibitory activity, acetylcholine.
