sideritis lanata/抗氧化剂

The phytochemical composition of the essential oils of three Sideritis libanotica subspecies, namely S. libanotica ssp. libanotica, S. libanotica ssp. linearis and S. libanotica ssp. michroclamys, all collected in Lebanon, was analyzed by GC and GC-MS. The diterpene sideridiol was recognized as the

Sideritis libanotica ssp. linearis was screened for the isolation of new natural antioxidant compounds. The antioxidant activity of flavones obtained from the methanol extract of the plant was evaluated in vitro using total antioxidant, reduction power and free radical scavenging activity. Results

In the present study, chemical compositions, antimicrobial and antioxidant activities of the essential oils of Sideritis erythrantha var. erythrantha (SE) and Sideritis erythrantha var. cedretorum (SC), which are endemic taxa in Turkey, were investigated. The essential oils obtained by

Sideritis euboea is a Greek plant that is traditionally consumed as a beverage (mountain tea). From in vitro studies, its extract has shown antioxidant and estrogenic activities. In our study we used S. euboea as an enriching food factor in order to produce a new functional food, a jelly dessert, in

Food irradiation technologies are used to reduce the risk of food bome diseases by eliminating pathogenic microorganisms, prolonging shelf life and reducing storage losses by delaying ripening, germination or sprouting. However, application of irradiation in food technology can negatively influence

Oxidative stress is involved in the pathophysiology of neurodegenerative diseases and aging. Many species of the genus Sideritis (mountain tea) are widely consumed in the Mediterranean region as herbal tea. This study evaluated the effect of supplementation of mice with herbal tea from Sideritis

This work was afforded from 2 points of view, phytochemical evaluation and relation to antioxidant activity and dietary burden of phenolics of a cup of "Mountain tea", a drink obtained by domestic infusion of Sideritis. Phytochemically, two extraction protocols using water and methanol as solvent

Nine 7-o-allosyl glucosides of 5,8-dihydroxy substituted flavones were isolated from a fraction of the methanol extract of the aerial parts of Sideritis raeseri Boiss et Heldr. subsp. raeseri. The structures were identified by spectroscopic methods. The antioxidant activity of this fraction,

This study was geared towards assessing the possible antioxidant, enzyme inhibitory, and cytotoxic activities of ethyl acetate, methanol, and water extracts of Sideritis ozturkii Aytaç & Aksoy. The phytochemical profiles of the studied extracts were characterised by HPLC-MS/MS. The methanol

Many publications have described the potential cardioprotective action of different medicinal plants, relating this effect with blood lipid levels. However, these publications do not justify the right amount of plant administered, which can vary greatly. Sideritis hyssopifolia is a little

Sideritis italica (Miller) Greuter et Burdet is a widespread Lamiacea in the Mediterranean region used in traditional medicine. Essential oils were antibacterial against nine ATCC and as many clinically isolated Gram-positive and Gram-negative bacterial strains. Antibacterial activity was also found

Sideritis caesarea (SC) Duman, Aytac & Baser is a member of the Lamiaceae family. The present study was designed to investigate the antioxidant properties of the aerial parts of island green tea SC against TCA effects in rats. Biomarkers selected for monitoring antioxidant capacity were the

The petroleum ether and acetone extracts of the aerial parts of Sideritis arguta afforded two new and six known diterpenoids with the ent-kaurane skeleton. The structures of the new diterpenoids were determined as ent-7alpha,18-diacetoxy-16beta-hydroxykaurane (diacetyldistanol) (1) and

OBJECTIVE The goals of this study were to monitor the effect of drinking of herbal tea from Sideritis clandestina subsp. clandestina for 6 weeks on behavioral and oxidant/antioxidant parameters of adult male mice and also to evaluate its phytochemical composition. METHODS The phytochemical profile
