Abstract:
Among the pathologic hypotheses of Alzheimer’s disease (AD), cholinergic deficit and oxidative stress have been implicated as major hallmarks. Therefore, inhibition of cholinesterase and oxidation are the two promising strategies in the development of a drug for AD. Basella alba, Blumea balsamifera and Curculigo orchioides are three available plants with numerous medicinal value. In this study these plants are used in this research to investigate its anticholinesterase, antioxidant and thrombolytic potentials. Anticholinesterase activity was measured by modified Ellman method. Antioxidant potentials were evaluated by the assay of reducing power, radical scavenging and ferrous reducing capability. Thrombolytic assessment is carried out by clot lysis method. The Methanolic extract showed strong anticholinesterase effect. Additionally, the extract exhibited pronounced reducing capacity, radical scavenging ability, and thrombolytic activity. Phytochemical screening of the extract revealed the presence of significant amount of total phenolics and flavonoids. The tested sample reflects potential antioxidative and anticholinesterase inhibitory effect which may warrant its effectiveness in the treatment of AD as well as clotting disorders.
