Impact of Extraction Solvent Polarity: Antioxydant Activity of Methanolic, Hydromethanolic and Aqueous Decocted Extracts of Algerien Thymelaea hirsuta (L.) Endl. Areal Parts

Thymelaea hirsuta (L.) Endl. , known as ‘Methnane’ in Algeria, is a widely medicinal plant used folk medicine. In the present study, vitro antioxidant activity of T. hirsta extracts and impact extraction solvent polarity on potential were investigated. Three types polar solvents with decreasing chosen; water for decocted extract, methanol-water at 50% absolute methanol macerated extracts. Total phenolic flavonoid contents evaluated showed high amount wihch decreases increasing polarity. Antioxydant was assessed different methods: ABTS assay evaluation scavenge activity, CUPRAC reducing power assessement reduction areal parts. The results that parts exhibited strong scavenging significant difference between terms their same line, most aqueous extract considerable followed by hydromethanolic methanolic potential. These findings suggest suitability phytochemical compounds from so, against several radicals ions.
