Chemical composition of essential oils from leaves and twigs of Pistacia lentiscus, Pistacia lentiscus var. chia, and Pistacia terebinthus from Turkey

WOS: 000225713900018The composition of the essential oils from the leaves and twigs of Pistacia lentiscus L., Pistacia lentiscus var. chia (L.), and Pistacia terebinthus L. of Turkish origin were analyzed by gas chromatography/mass spectrometry (GC/MS). Seventy-seven constituents were characterized from the essential oil of P terebinthus leaves with alpha-cadinol (6.9%), phytol (5.4%), delta-cadinene (5.1%), alpha-terpineol (5.0%), and bornyl acetate (4.4%) as major constituents. Germacrene D (10%), beta-pinene (7.5%), bornyl acetate (6.0%), alpha-cubebene (5.9%), and cubebol (5.4%) were found to be the main components among the 61 compounds characterized in the essential oil of P terebinthus twigs. Forty-six compounds were characterized from the essential oil of P lentiscus twigs with sabinene (23.2%), alpha-pinene (19.4%), germacrene D (14.1%), limonene (6.9%), beta-phellandrene (6.5%), terpinene-4-ol (5.7%), and beta-caryophyllene (5.7%) as the main constituents. Terpinene-4-ol (29.2%), beta-caryophyllene (29.2%), and p-cymene (7.1%) were identified as the major components among the 64 compounds characterized in the essential oil of P lentiscus leaves. Sixty-eight compounds were found on the essential oil of P lentiscus var. chia leaves with germacrene D (20.1%), myrcene (13.9%), beta-caryophyllene (10.8%), and alpha-terpinyl acetate (4.8%) as the major constituents. Myrcene (27.4%), germacrene D (21.7%), and beta-caryophyllene (7.2%) were found to be the main components among 50 compounds characterized in the essential oil of P lentiscus var. chia twigs

Composition of essential oil and fatty acids and antioxidant assays of Psephellus pyrrhoblepharus (Boiss.) Wagenitz

WOS: 000489251100005In this study, the essential oil of Psephellus pyrrhoblepharus (Boiss.) Wagenitz was obtained by hydrodistillation using a Clevenger-type apparatus. the oil was analysed by GC and GC/MS system. the components were separated as for adherence to the column and evaluated as for relative rate. Mass spectra of each component were taken. GC and GC/MS analyses of the essential oil from P. pyrrhoblepharus determined the identification of 59 components representing 84% of the oil. With this analysis, the major component was found as hexadecanoic acid (17.1%). Subsequent to this component, other major components were spatulenol (10.3%), caryophyllene oxide (9.6%) and heptacosane (5.2%). in addition to this, fatty acid methyl esters (FAMEs) from P. pyhhoblepharus were prepared for analysis of fatty acids. By this test the amount of saturated fatty acids (SFA) were 31.37% with major fatty acid palmitic acid (12.86%). Also, the antioxidant assays DPPH, ABTS, ORAC, CUPRAC and reducing power assay were carried on methanol:water, n-hexane, chloroform and ethyl acetate extracts of P. pyrrhoblepharus. With the assays, ethyl acetate extract of P. pyrrhoblepharus was found as the most antioxidant extract. These data show that the plant is valuable for further studies

Composition of the essential oil of Arbutus unedo

WOS: 000175404700012Water-distilled essential oil from leaves of Arbutus unedo L of Turkish origin was analyzed by GC/MS. Thirty-seven constituents were characterized with (E)-2-decenal (12.0 %), alpha- terpineol (8.8 %), hexadecanoic acid (5.1 %), and (E)-2-undecenal ( 4.8 %) as the major constituents

The Essential Oil Constituents of Ranunculus marginatus d'Urv. var. trachycarpus (Fisch. & Mey.), From Turkey

Abstract: The essential oil obtained by hydrodistillation from Ranunculus marginatus var. trachycarpus (Ranunculaceae) from Turkey was analyzed by GC and GC-MS. Thirty-six compounds were characterized in the oil of R. marginatus var. marginatus. Main compounds were ?-terpinyl acetate (18.9 %), phytol (11.1 %), hexadecanoic acid (10.0 %) and ß-sesquiphellandrene (8.7 %). © 2014, Har Krishan Bhalla & Sons

The Effects of Flaxseed on Menopausal Symptoms and Quality of Life

WOS: 000353624200006PubMed ID: 25882265The purpose of this study was to analyze the effects of flaxseed on menopausal symptoms and quality of life throughout the menopausal period. The empirical research was conducted in an obstetrics and gynecology outpatient department of a university hospital and involved 140 menopausal women who were divided into 4 groups. The menopausal symptoms decreased and the quality of life increased among the women who used flaxseed for 3 months
