The pathogenesis of nonalcoholic steatohepatitis (NASH) is not fully understood, but many studies have suggested that oxidative stress plays a key role. The methionine- and choline-deficient diet (MCD) administration model can reproduce histopathological features of human NASH and is widely used for investigating NASH. C57BL/6J mice have been used in many studies, but strain differences in path...

This study was designed to examine the chemical composition and in-vitro antioxidant activity of the essential oil and methanolic extract of Teucrium orientale subsp. taylori. The GC and GC-MS analysis of the essential oil resulted in determination of 40 components representing 96.4% of the oil. The major constituents of the oil were linalool (28.6%), caryophyllene oxide (15.6%), 1,8-cineol (4....

Nepeta L. is one of the important genus in Lamiaceae family. It includes ca. 300 herbaceous species and mostly grows Eurasia. represented Turkey by 40 taxa these 16 are endemic. commonly utilized traditional medicine local people, primarily as spasmolytic, diuretic, bronchodilator agents. As a consequence studies on taxa, terpenoids flavonoids have been identified most common components. In thi...

Abstract Bunium crassifolium Batt. ( B. ) (Apiaceae) is an extremely rare endemic species from the North East of Algeria. In this study, we extracted volatile organic compounds (VOC) aerial parts using Agilent G1888 network headspace sampler coupled with 7890 GC system. The results revealed presence twenty-two (22) compounds, twenty (20) which were identified as representing 97.48% total compos...

In this study, the variability of essential oil composition in different parts of summer savory was investigated. Extraction of essential oils from air-dried leaves and healthy seeds was done using water-distillation in Clevenger-type apparatus for 4 h. In total, 23 and 24 components were identified in the leaves and seeds of summer savory, respectively. Carvacrol (46.023%), Estragole (Methyl C...

The chemical composition and cytotoxic activity of the essential oils extracted from leaves of Croton matourensis and flowers and leaves of Croton micans were investigated. GC-FID and GC-MS analysis revealed that forty six compounds comprised 95.5 % of C. matourensis essential oil, with the main components being fenchyl acetate (19.5%), methyleugenol (14.2%), isoelemicine (11.3%), elemicine (7....

The leaf essential oils of six members of the Annonaceae from Monteverde, Costa Rica (Desmopsis bibracteata, Desmopsis microcarpa, Guatteria costaricensis, Guatteria diospyroides, Guatteria oliviformis, and Unonopsis costaricensis) have been obtained by hydrodistillation and analyzed by GC-MS in order to compare and contrast the volatile chemical compositions of these species. The essential oil...

Herbivory, mechanical injury or pathogen infestation to vegetative tissues can induce volatile organic compounds (VOCs) production, which can provide defensive functions to injured and uninjured plants. In our studies with 'McNeal' wheat, 'Otana' oat, and 'Harrington' barley, plants that were mechanically injured, attacked by either of two Oulema spp. (melanopus or cyanella) beetles, or infecte...
