The phenolic content of the RE was

The phenolic content of the RE was evaluated using the 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.
