The present study estimated in vitro antioxidant activities of methanolic extracts of some Algerianmedicinal plants (Saccocalyx satureioïdes, Teucrium polium and Salvia verbenaca) (Lamiaceae) using Folin–Ciocalteu, ferric-reducing/antioxidant power (FRAP) and 2,2- diphenyl-1-picrylhydrazyl (DPPH) radical-scavenging assays. The results showed that methanolic extract of Teucrium polium with a total content of polyphenols (3.81 GAE/g) and an IC50of 5.70μg/mLwas more antioxidant. In power reduction, the antioxidant activity of T.poliumand S.satureioïdes extract’s, at all the concentrations were average compared to controls used (BHA, BHT).
