In this study, we aimed to determine biochemical contents of white (Morus alba L.) and black (Morus nigra L.) mulberry genotypes grown in the Hakkari region. At the end of the study, organic acids, phenolic compounds, sugars, vitamin C and antioxidant capacities of mulberry species were determined. Black mulberry genotypes were found to contain higher antioxidant capacity than white mulberry genotypes. The highest antioxidant capacity was detected in the 30YK03 (25.55 mu moITE/g) black mulberry genotype. While phenolic compounds varied in mulberry species, especially gallic acid (57.78 mg/100g), chlorogenic acid (53.13 mg/100g), and rutin (37.77 mg/100g) had the highest values. Malic acid was found to be higher than other organic acids and was found to be 13.51 g/100g in the highest 30HK03 genotype. Although sugar contents varied in mulberry species, glucose was determined higher than fructose and sucrose in mulberries.

Background: Salvia L., the largest genus of Lamiaceae, includes about 1000 species, widespread throughout the world. This genus is represented, in Turkish flora, by 99 species and 113 taxa, 58 of which are endemic. Some members of this genus are of economic importance since they have been used as herbal tea, flavouring agents in perfumery and cosmetics. Some sage (Salvia L.) species has been credited with a long list of medicinal uses: e.g. spasmolytic, antiseptic, astringent. Objective: In present study, essential oil composition of some sage (Salvia L.) species cultivated in Izmir (Turkey) was investigated. Sage species have recently become more common in Turkey and sage cultivation is increasing especially in the Aegean Region. Material and Methods: The species of Salvia fruticosa Mill., Salvia officinalis L., Salvia sclarea L., hybrid (Salvia fruticosa Mill. x Salvia officinalis L.) and Salvia dichroantha L. were used in the study. Essential oils were extracted according to hydro distillation method with clevenger type apparatus and analyzed using GC-FID and GC-MS system. Results: Essential oil contents of Salvia fruticosa MM. was 3.86%, Salvia officinalis L. 2.42%, Salvia sclarea L. 0.5%, Salvia fruticosa Mill. x Salvia officinalis L. 2.84% and Salvia dichroantha L. 0.19%. The number of components in essential oils were detected 22, 16, 14, 20 and 16 respectively. The chemical composition of the essential oils in Salvia fruticosa Mill. 1,8-cineole (57.18%), Salvia officinalis L. beta-thujone (34.59%), Salvia sclarea L. linalyl acetate (46.77%), Salvia fruticosa MM. x Salvia officinalis L. 1,8-cineole (21.42%) and beta-thujone (18.37%) and Salvia dichroantha L. beta- caryophyllene (23.11%) and sabinyl acetate (21.87%).
