Essential Oils of Four Turkish Wild-Growing Labiatae Herbs: Salvia cryptantha Montbr. et Auch., Satureja cuneifolia Ten., Thymbra spicata L. and Thymus cilicicus Boiss. et Bal.

Abstract The essential oils obtained by hydrodistillation of four Labiatae herbs, namely Salvia crytantha. Montbr. et Auch., Satureja cuneifolia Ten., Thymbra spicata L. and Thymus cilicicus Boiss. et Bal. growing wild in Middle Anatolian provinces of Turkey, were analyzed by GC and GC/MS. Fifty-four compounds were identified in S. cryptantha oil of which camphor (18.1%), 1,8-cineole (17.8%), and bornyl acetate (11.4%) were major. In the oils of S. cuneifolia, 38 compounds were identified, with thymol (43.6–65.5%), carvacrol (4.7–31.2%), γ-terpinene (trace-13.7%) and p-cymene (trace-11.5%) being dominant. Of the 33 compounds identified in T. spicata oil, the main components were p-cymene (22.1%), γ-terpinene (21.4%), carvacrol (21.1%) and thymol (11.8%). The oil of T. cilicicus, which contained 35 constituents, was found to be rich in α-terpineol (16.4%) and camphor (9.7%).

Essential Oil Constituents of Trachyspermum copticum (L.) Link Fruits

ABSTRACT The essential oil, which was obtained by steam distillation of fruits of Trachyspermum copticum (L.) Link harvested in Turkey, was analyzed direcdy by GC and GC/MS. Twenty-seven compounds were identified of which thymol (61%) was present in greatest quantity. Other major components were p-cymene (15.6%) and γ-terpinene (11.9%)

The Essential Oils of Calamintha nepeta subsp. glandulosa and Ziziphora clinopodioides from Turkey

ABSTRACT The essential oils of two wild growing plants used as herbal tea and mintlike spice in Turkey, Calamintha nepeta (L.) Savi subsp. glandulosa (Req.) P. W. Ball and Ziziphora clinopodioides Lam. were analyzed by GC and GC/MS. Twenty-three components were identified in both oils with pulegone (42.0%) and piperitenone (40.4%) being the major components in the Calamintha oil, and pulegone (60.2%), menthone (13.6%) and menthol (10.9%) being the major components in the Ziziphora oil were the main components.

Essential Oil Constituents of Achillea biebersteinii Afan.

ABSTRACT The essential oil composition of Achillea biebersteinii Afan., collected in Turkey, is reported. Using GC and GC/MS, forty-seven compounds were found of which more than 60% of the oil was represented by 1, 8-cineole (46.1%) and camphor (17.6%). The other major constituents were α-terpineol (8.2%), borneol (3.4%), sabinene (3.2%) and terpinen-4-ol (3.1%).

Volatile Constituents of the Essential Oil of Acorus calamus L. Grown in Konya Province (Turkey)

Abstract The essential oil of Acorus calamus L. roots obtained from Konya (Beysehir) was analyzed by GC/MS. Forty-three components representing 71.16% of the oil were identified. Preisocalamendiol (17.3%), isoshyobunone (13.0%), 1,4-(trans)-1,7(trans)-acorenone (10.5%), camphor (5.9%), 2,6-diepishyobunone (2.6 %) and β-gurjunene (2.5%) were the major constituents.

Composition of the Essential Oil of Echinophora tenuifolia L. ssp. sibthorpiana (Guss.)Tutin from Turkey

Abstract Echinophora tenuifolia L. ssp. sibthorpiana (Guss.) Tutin, a member of the Umbelliferae family, is a typical aromatic plant of central Turkey. The hydrodistilled essential oil of aerial parts of the plant was analyzed by GC and GC/MS. Thirty-seven compounds representing 95.7% of the oil were established. Methyl eugenol (36.6%), γ-3-carene (36.6%), p-cymene (7.6%) and α-phellandrene (6.1%) were the main components.

Volatile Constituents of Essential Oils of Salvia aucheri Benth. var. canescens Boiss. et Heldr. and S. tomentosa Mill. Grown in Turkey

Abstract Composition of water-distilled essential oils of Salvia aucheri var. canescens and S. tomentosa growing wild in Turkey were analyzed by GC and GC/MS. Forty-four and sixty components were identified in the both oil constituting 96.3% and 97.4% of the total components detected, respectively. 1,8-Cineole (38.9–21.2%), camphor (18.3–24.5%), camphene (7.9–4.3%)and (J-pinene (4.3–3.3%) were found to be the major components in both the oils.

Essential Oil of Thymus sipyleus Boiss. subsp. sipyleus var. sipyleus

ABSTRACT Water distilled essential oils from aerial parts of Thymus sipyleus subsp. sipyleus var. sipyleus, an endemic species of Turkey, collected from five different localities were examined by capillary GC and GC/MS. Seventy-seven compounds were characterized. Geranial (8.39–36.97%) and neral (3.08–25.56%) were major constituents of two of these lemon-scented oils. Linalool (21.77%) and α-terpineol + isoborneol (25.48%) were the main constituents in the oils of two collections, respectively.

Volatile Constituents of the Leaves of Persea gratissima Gaertner. A Source of Methyl Chavicol

ABSTRACT The essential oil of the leaves of Persea gratissima Gaertner cultivated in Turkey was investigated using GC and GC/MS. Twenty-nine of the thirty-six compounds were identified. The bulk of the oil is represented by methyl chavicol (78%). The content in this allylphenol appears to be higher than that normally found in die tarragon and basil oils.

The Essential Oil Composition of Turkish Laser trilobum (L.) Borkh. Fruits

ABSTRACT The chemical composition of the fruit essential oil of Laser trilobum growing wild in Turkey was determined by capillary GC and GC/MS. Among the twenty two components identified, limonene (60.70%) and perillaldehyde (32.30%) were found to be the major constituents.
