Folin–Ciocalteu reagent. It was about 112 mgGAE/g extract. This amount is less than that found by Erkan et al. (2008) on the methanolic rosemary extract and which is about 162 mg GAE/g extract. This difference may be the cause of the higher polarity of methanol used in their study and which allows better extraction of the polar phenolic compounds. Therefore, the nature of the solvent used in the extraction mayaffect the phenolic content (Liu et al., 2007). The choice of ethanolin our study was based on its food security character (Nor Aini et al.,2008). Other factors may also affect the polyphenols composition of the RE mainly genetics, season of collection and the maturity of the plant.
