| Investıgatıon Of Antıoxıdant Constıtuents In Sage Leaf (Salvia Spp.)
In this study, antioxidant compounds and essential oils of Sideritis persoliata L. and Salvia fruticosa M. sage samples were investigated. The Sideritis persoliata L. species, a herb widely available in and around Bergama, had previously not been extensively researched. In addition, the Salvia fruticosa M. species, which grows naturally in the island of Marmara, was also closely examined.
The antioxidants of both species of sages were extracted using 80% methanol. Extracts were analized by LC/MS, the compounds indentified and their ratio were as follows in Sideritis persoliata L. species; luteolin (62.41%), quercetin dihidrat (24.35%), cinnamic acid (13.24%) and in Salvia fruticosa M. species; quercetin dihidrat (2.47%), apigenin (2.53%), cinnamic acid (2.80%), luteolin (3.34%) and rosmarinic acid (89.10%).
The essential oils present in the sage samples were obtained using continuous distillation extraction. The exracts were analized by GC/MS. As a result of the analysis, 24 qualitative compounds were detected, the main being: α-pinene (5.15%), camphor (0.06%), caryophyllene (93.03%), linalool (0.06%), 1,8-sineol (eucalyptol) (1.68%) in Sideritis persoliata L. species. And 50 qualitative compounds were detected, the main being: α-pinene (12.58%), camphor (1.56%), caryophyllene (4.29%), linalool (0.17%), 1,8-sineol (eucalyptol) (52.60%), 2-β-pinene (0.47%), borneol (7.66%), camphene (18.37%), β-myrcene (2.42%), linalyl acetate (0.04%), terpinene-4-ol (0.07%), thujone (0.10%) in Salvia fruticosa M. species.
In conclusion, Sideritis persoliata L. containing a fewer number of essential compounds compared to Salvia fruticosa M. furthermore, both species of Sage revealed rich levels of antioxidants.
