Phytochemical Characterization and Assessment of Antioxidant and Anti-Alzheimer Effects of Algerian Seseli Tortuosum.

HPLC analysis, phytochemical screening, thin layer chromatography, polyphenols and flavonoid contents were conducted to determine the bioactive contents of the Algerian Seseli tortuosum plant. Antioxidant activity was tested using DPPH and ABTS scavenging assays, reducing power, phenanthroline and silver nanoparticle (SNP) assays. The anti-Alzheimer's activity of extracts was also performed in vitro and in silico.
