Objective: To assess antioxidant activities of different aerial parts of Thymelaea hirsuta (T.\udhirsuta) from west Algeria, and to search for new sources of safe and inexpensive antioxidants.\udMethods: Samples of leaves, stems and flowers from T. hirsuta were tested for total phenolic\udcontent, flavonoids content, and evaluation its total antioxidant activity, were done using the\udspectrophotometric analyses.\udResults: Results of preliminary phytochemical screening of leaf, flower and stem of T. hirsuta\udrevealed the presence of tannins, alkaloids, steroids, saponins, coumarins, reducteurs compound\udand anthraquinones. The total phenolics and flavonoids were estimated. The aqueous extracts of\udthe aerial parts of T. hirsuta showed potent in vitro antioxydant activities using various models\udviz, DPPH scavenging assay, ferric reducing antioxidant power (FRAP) and ABTS radical scavenging\udactivity.\udConclusions: On the basis of the results obtained, T. hirsuta extracts are rich sources of natural\udantioxidants appears to be an alternative to synthetic antioxidants and this justifies its therapeutic\udusage
