Essential Oil Composition of Two Grammosciadium DC. Species, G. platycarpum (Boiss et Hausskn) Schischk and G. macrodon Boiss (Apiaceae), from Turkey

Purpose: To investigate and compare the essential oil composition of two Grammosciadium species obtained by hydrodistillation Methods: The essential oil of the aerial parts of two species was obtained by hydrodistillation and analyzed by gas chromatography (GC) and gas chromatography - mass spectrometry (GC-MS). Results: In G. platycarpum, twenty-seven compounds were identified representing 99.3 % of the total oil. The major constituents of the oil were limonene (28.4 %), β-pinene (16.1 %), β-selinene (15.9 %), δ- 3-carene (11.2 %), α-farnesene (6.0 %) and p - cymene (4.7 %). The oil of G. macrodon contained thirty-seven components representing 94.4 % of the total oil, with caryophyllene oxide (15.9 %), germacrene - D (12.4 %), β-caryophyllene (11.5 %), δ-3 - carene (10.1 %) and cyclohexane (4.6 %) as the main constituents. Conclusion: The essential oil composition of G. macrodon was analysed for the first time, the most abundant constituents being caryophyllene oxide, and cyclohexane

Essential oil composition, antioxidant and antifungal activities of Salvia sclarea L. from Munzur Valley in Tunceli, Turkey

The essential oil composition and in vitro antioxidant and antifungal activity of the Salvia sclarea L. from Munzur Valley in Tunceli, Turkey were evaluated in this research. The in vitro antifungal activity of ethanol, hexane and aqueous extracts of S. sclarea against pathogen fungi Epicoccum nigrum and Colletotrichum coccodes were investigated. The essential oil of aerial parts of S. sclarea was obtained by hydrodistillation and was analysed by GC and GC-MS. Total antioxidant status was determined by using Rel assay diagnostics TAS assay kit (Lot.RL024) by Multiscan FC (Thermo). 33 compounds were identified representing the 85.0% of the total oil. The most abundant components (>5%) of the S. sclarea essential oils were caryophyllene oxide (24.1%), sclareol (11.5%), spathulenol (11.4%), 1H-naphtho (2,1,6) pyran (8.6%) and b-caryophyllene (5.1%). The best antifungal and antioxidant effect was seen in ethanolic S. sclarea extract. It can be said that Salvia sclerae could be used as natural antioxidant
