Phytochemical Analysis and Antioxidant Activity of Tetraclinis Articulata Leaves Extract from the Fergoug Forest in Mascara, Algerian Western Region

Antioxidants derived from plants, particularly phenolics, have garnered significant attention owing to their potential advantages for human health. The purpose of this study was to assess the phytochemical composition and in vitro antioxidant activity of the aqueous extract from Tetraclinis articulata leaves. Qualitative examinations were conducted on leaf extracts to identify the total polyphenols. Their concentration was determined spectrometrically using the Folin−Ciocalteu procedure. The antioxidant efficiency was tested using the 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical-scavenging method. Phytochemical screening indicated the presence of phenolics, with a total polyphenol concentration of 57.5 mg EGA/g DW. The DPPH method showed a strong radical scavenging activity, exhibiting an inhibition percentage of 88,98% at a concentration of 1mg/ml.  Based on these findings, it is evident that T. articulata leaves are abundant in secondary substances contributing to their antioxidant activity. Consequently, this plant holds promise as a potential candidate for the formulation of natural drugs or additive preparations.
