Abstract
The present study determined the neuroprotective potential of the alcoholic and aqueous extracts of Pandanus clementis Merr. (Pandanaceae) to protect the neuroblastoma SH-SY5Y cells against amyloid-beta1-42 (Aβ) cytotoxicity. Inhibition of Aβ aggregation was determined by Thioflavin T (ThT) assay, and in vitro neuroprotective cell viability, intracellular reactive oxygen species (ROS), and mitochondrial membrane potential (MMP) were evaluated with human neuroblastoma SH-SY5Y cells insulted with Aβ. Chromatographic separation on the alcoholic extract yielded known phytosterols. Results showed that pretreatment of the SH-SY5Y cells with the P. clementis extracts increased cell viability and MMP, and decreased ROS, suggesting protective effects. Hence, P. clementis extract has promising neuroprotective therapeutic potential.
