| Abstract: | In this study, the essential oil and the phenolic composition along with the antioxidant activity of R. officinalis L. and S. fruticosa Miller, collected in Zakynthos island (Ionian Sea, Greece), were investigated. The essential oil composition of the plants was characterized by the presence of 1,8-cineole. Mean values of the antioxidant activities of rosemary and sage essential oils indicated slight differences. The antioxidant activity of sage oil was correlated with the oxygenated sesquiterpenes and diterpenes concentrations. Concerning the methanolic extracts, a close relationship between the phenolic content and the development stage during vegetative cycle of these plants was observed. The identified flavonoids, except rutin, seemed to increase with the advancement of developmental stages, while phenolic acids followed an opposite pattern. The antioxidant activity was correlated with the amount of total phenolic content. |
