In this research, the chemical composition and biological activities of various extracts obtained from whole parts Sedum sediforme (Jacq.) Pau were compared. The amounts total phenolic flavonoid components in crude determined by expression as pyrocatechol quercetin equivalents, respectively. All (petroleum ether, acetone, methanol, water) S. showed strong antioxidant activity four tested methods. Particularly, IC50 values methanol extract, which was richest terms contents, found to be lower...
Abstract Representatives of the Achillea genus are widely used as foods or nutraceuticals. Considering increasing demand for herbal dietary supplements with health promoting effects, objective this research was to evaluate chemical composition and biological activities essential oils obtained from sixteen species ( A. biebersteinii , wilhelmsii subsp. aleppica zederbaueri vermicularis monocephala nobilis goniocephala sintenisii coarctata kotschyi millefolium lycaonica spinulifolia...
Abstract Allium species are widely consumed as food all over the world. The phenolic profile of ethanol extracts aerial parts and roots 12 species, collected from five different Eastern Anatolia regions, were studied using LC‐MS/MS. In vitro antioxidant, anticholinesterase, cytotoxic antimicrobial activities also tested. multivariate analyses performed principal component hierarchical cluster analyses. Seventeen 27 standard compounds detected in species. major components mainly identified...
The essential oil of hyssop is widely used in food, pharmaceutical and cosmetic industries throughout the world. Therefore, it very important to know chemical characteristics for economic use enhanced performance end products. This study was carried out determine antimicrobial antioxidant activities Hyssopus officinalis (L.) (Lamiaceae) collected from wild Southeast Anatolian, Turkey. Chemical compositions hydrodistilled oils obtained leaves were analyzed by gas chromatography-mass...
This study investigates the antioxidant, antimicrobial, and anticancer properties of Bellevalia sosonii, an endemic species with limited prior pharmacological research. The findings reveal that B. sosonii possesses notable radical-scavenging activity, particularly in subterranean acetone extract, which exhibited strongest antioxidant effect both ABTS (IC₅₀: 1.9 µg/ml) DPPH 11.6 assays. extract also had highest total phenolic content (288.5 ± 1.7 µg GAE/mg extract), while methanol contained...
This study was the first fatty acid analysis and biological activity report on an endemic Achillea species, cappadocica Hausskn. et Bornm. The major compounds in were identified as oleic (34.7 %), palmitic (23.1 linoleic acids (20.6 %). methanol water extracts indicated higher ABTS cation radical scavenging than that of \alpha-tocopherol BHT at 100 \mu g/mL. acetone extract showed 70.62 % inhibitory against butyrylcholinesterase 200 exhibited moderate antimicrobial activity.
The purpose of the present work was to calculate phenolic and fatty acids profiles by LC-MS/MS GC/MS with their antioxidant, anticholinesterase antimicrobial activities, aflatoxin contents Malva neglecta Malvella sherardiana. M. sherardiana were determined LC-MS/MS. Malic 4-OH benzoic found be most abundant compounds in sherardiana, respectively. On other hand, essential oils composition analysis. methanol extracts plants showed highest effect all antioxidant assays this study. extract...
Context: In Turkey, Veronica species (Plantaginaceae) have been used as a diuretic and for wound healing in traditional medicine.Objective: To examine the fatty acid essential oil profiles, antioxidant, anticholinesterase, antimicrobial, DNA damage effects of thymoides P.H. Davis subsp. pseudocinerea M.A. Fischer potential source natural active compounds.Materials methods: GC/MS was to analyze obtained from whole plant. The antioxidant activity evaluated by β-carotene-linoleic test system,...
AbstractIn the present study, seven thyme species Origanum onites, O. vulgare var. hirtum, gracile, syriacum, Satureja hortensis, Thymbra spicata, and Thymus vulgaris were used. The essential oils of these plants obtained by hydrodistillation method. Antimicrobial activities against microorganisms, including multiple antibiotic-resistant bacteria, investigated using disc diffusion All used in this study very effective Gram-positive Gram-negative which included resistant strains. tested...
The objectives of this study were to define the phenolic and fatty acid profiles, anticholinesterase, antioxidant, antimicrobial activities, total phenolic-flavonoid contents Lycopsis orientalis Tragopogon latifolius var. angustifolius which have been used as food source supplement in Anatolia never examined before. Rosmarinic quinic acids (21.11 11.46 mg g–1 extract, respectively) found be most abundant constituents L. T. among studied 27 compounds by liquid chromatography tandem mass...
The genus Nepeta (Lamiaceae) and Achillea (Asteraceae) are widely distributed in Turkey. In this study, the essential oils of italica L. filipendulina LAM. collected from Dicle district Diyarbakir province Southeast Anatolia Hakkari East Turkey, were obtained by hydrodistillation aerial parts. analyzed gas chromatography-mass spectrometry GC Clarus 600-MS 600 C (Perkin Elmer) microelements Perkin Elmer Optima 2100 DV ICP OEMS, also antioxidant activity DPPH radical scavenging assay. showed...
Bu çalışmada, anason (Pimpinellaanisum L.) ve kimyon (Cuminum cyminum) tohumlarınınuçucu yağ bileşenleri ile bu yağların antimikrobiyal antioksidanözelliklerinin belirlenmesi amaçlanmıştır. Uçucu GC / MS cihazıile belirlenmiştir. Yağların özellikleri disk difüzyon yöntemiile Gram pozitif (Staphylococcus aureus ATCC 25923, Streptococcuspyogenes 19615), negatif (Escherichia coli 25922, Pseudomonasaeruginosa 27853) bakteri maya (Candida albicans 10231)kullanılarak Antioksidan ise DPPH serbest...
In this study, investigation on the essential oils and ethanol extracts of naturally grown cultivated Satureja macrantha samples were reported. The oil, flavour terpenoid-steroid-flavonoid contents S. determined by GC-MS their phenolic LC-MS/MS. Besides, biological activities investigated for antioxidant, anti-Alzheimer, antimicrobial, cytotoxic, antityrosinase, antiurease, antielastase anticollagenase properties. content antioxidant capacity sample higher than those sample. According to...
Kabaklı Göleti'nden (37° 55' 23K, 40°17' 40D, Diyarbakır) izole edilen ve Chlorella vulgaris Beyerinck Chroococcus limneticus Lemmermann olarak tanımlanan mikroalg türlerinin metanol ekstraktlarının antimikrobiyal, antioksidan mutajenik aktiviteleri araştırıldı. En yüksek aktivite, 100 µg/ml konsantrasyonunda C. (%36,63) (%28,48) için ABTS•+ analizinde gözlendi. DPPH CUPRAC analizleri zayıf aktivite gösterdi. Antioksidan pozitif kontrollerle karşılaştırıldığında her iki tür de önemli...
The mutagenicity and antimutagenicity of leaves flower extract Cynara syriaca Boiss were studied with Ames assay in Salmonella typhimurium TA98 TA100 strains. While did not show any mutagenic effects against all the tester strains or without metabolic activation, showed effect strain activation.
