Pelargonium quercetorum is a medicinal plant traditionally used for treating intestinal worms. In the present study, chemical composition and bio-pharmacological properties of P. extracts were investigated. Enzyme inhibition scavenging/reducing water, methanol, ethyl acetate assayed. The also studied in an ex vivo experimental model colon inflammation, this context gene expression cyclooxygenase-2 (COX-2) tumor necrosis factor α (TNFα) Additionally, cancer HCT116 cells, transient receptor...
"Sulmona Red Garlic" is a well-known Italian traditional product. Bulbs, used for culinary purposes, have been largely investigated their medicinal properties whereas aerial bulbils are usually removed as waste material. Here, the first time, chemical composition and biological of hydroalcoholic extract from were investigated. Complementary information on metabolite obtained using both NMR based untargeted HPLC-DAD targeted methodologies. The analysis revealed presence sugars, organic acids,...
In the present study, chemical compositions of essential oils from seeds and leaves laurel (Laurus nobilis L.) were evaluated using GC-GC/MS system. Sixty nine different compounds identified constituting 86.7% total oil seed, while 76 determined, 95.8% extracted leaves. The major included eucalyptol (17.2%), α-terpinyl acetate (9.0%), caryophyllene oxide (6.1%), spathulenol (5.0%) methyl eugenol (4.2%), 41.5% oil. However, (18.0%), (13.1%), sabinene (7.8%), α-pinene (4.5%), 2...
A sensitive, reliable, simple and rapid analytical method was developed for the determination of arsenite [As(III)], arsenate [As(V)] arsenobetaine (AsB) species using ion chromatography combined with inductively coupled plasma-mass spectrometry (IC-ICP-MS). Inorganic organic arsenic were separated an anion exchange column (Dionex AS9) a 50 mM sodium bicarbonate mobile phase (pH 10) at flow rate 1.0 mL min−1. %RSD values found to be lower than 5.1% all species. The limits detection (LOD)...
The chemical composition, antimicrobial and antioxidant properties of the essential oil (EO), obtained from leaves Vaccinium myrtillus naturally grown in northernmost Turkey were determined by GC GC-MS differences discussed with help chemotaxonomy. plant samples hydro-distilled to produce yields 1%. Nineteen components identified representing 96.4% oil. main compounds EO V. were; 1,8-cineole (38.6%), α- pinene (21%), linalool (19.5%), α-terpineol (5.8%). extract was screened for their...
In this study, the essential oils of Helichrysum graveolens species from Turkey were investigated and 72 components identified by GC, GC-MS. Essential oil was hydrodistilled using Clevenger apparatus aerial parts plants collected natural habitats. The yield is very low 0.1 (v/w). Seventy two constituents comprised 82.97 % total extracted graveolens. predominant compounds as a-cubebene (10.5 %), b-caryophyllene (9.4 azulene-octahydro (7.5 caryophyllene oxide (8.2 %). results discussed in view...
This study aimed to describe the chemical composition of Essential Oil (EO) aerial parts E. maritimum, and verify its antimicrobial antioxidant properties. The EO characterization was simultaneously obtained by GC/FID GC/MS. Thirty-one compounds corresponding 93.3% were identified in maritimum. Spathulenol (22.0%), aromadendrene (18.3%), humulene epoxide (6.6%), β-humulene (4.8%) main EO. activities determined against 3 gram-positive bacteria, 4 gram-negative 2 yeast species using...
Abstract Helichrysum genus is currently known and some are used in folk medicines. In Flora of Turkey, it represented with 27 taxa, 15 which endemic to Turkey. Essential oil was obtained from the aerial parts plant yielded 0.1 % (v/w). The chemical composition essential noeanum analyzed by GC GC-MS system. Fourty one constituents were identified, representing 95.88 total oil. g-Gurjunene (11.06 %), spathulenol (9.90 alloaromadendrene (7.53 b-caryophyllene (7.10 %) major compounds determined H.
Teucrium polium L. is a plant with various claims of ethnobotanical use, primarily for in-flammatory diseases. Chemical studies have already isolated different types terpenes from the species, and established pharmacological potential. The present study evaluated components T. essential oil cultivated in Algerian Saharan Atlas. GC-MS identified major as Fenchone (31.25%), 3-Carene (15.77%), cis-Limonene oxide (9.77%), Myrcene (9.15%). In silico prediction, molecules more than 1% abundance...
The chemical composition, antimicrobial and antioxidant properties of the essential oils from leaves endemic Thymus leucostomus naturally grown in Turkey were investigated differences discussed by means chemotaxonomy. Twenty-six components identified representing 98.8% oils. main compounds oil T. were: o-cymene (30.6%), carvacrol (9.6%), thymol methyl ether (7.2%), limonene (6.8%). Essential was screened for their activities against 7 bacteria 2 yeast species using disc-diffusion MIC...
This study aimed to describe the chemical composition of essential oil (EO) stems, leaves and flowers A. maritima collected from Turkey, verify its antimicrobial antioxidant properties. The EO was analyzed by GC-FID GC-MS. Fifty-nine compounds representing 98.1% were identified. activities determined against seven bacteria two yeast species using disc diffusion MIC techniques. According results, it observed that there no effect Gram-positive bacteria. showed a low (8–9 mm) Gram-negative...
In this study, the chemical composition of essential oils obtained from aerial parts Thymus longicaulis subsp. naturally grown in Turkey were analyzed by GC and GC-MS differences terms chemotaxonomy discussed. The main compounds T. 1,8-cineole (30.1%), linalool (18.0%), β-pinene (17.3%) (E)-β-ocimene (%12.6%) Hierarchical cluster analysis was performed examining oil studies 34 samples belonging to genus Thymus, including Sinop sample. results study discussed with other taxa genus.
In this study, Helichrysum plicatum subsp.plicatum and subsp.polyphyllum (Asteraceae) represented in the genus were investigated for taxonomical purposes.The specimens belonging to both taxa collected different locations from Turkey view of morphological, morphometrical, anatomical palynological features determine similarity differences between two taxa.Anatomical studies carried out on stem root characters with Light microscope illustrated.Pollen observed Scanning Electron Microscopy...
In this study, S. nigra L. and ebulus (Adoxaceae) species belonging to the Sambucus genus were examined. Species of collected from northern Turkey anatomical comparisons made. Stem leaf anatomy examined by light microscopy. The plants have woody stem anatomy. druse crystals which are main characters observed in taxa. Differences found number cells vascular bundles, arrangement druze crystals, shapes abaxial adaxial epidermis leaf. addition, differences margin shape collenchyma cell numbers on stem.
In the present study, chemical composition of essential oils obtained from leaves Laurus nobilis naturally grown in Turkey were evaluated using by GC and GC-MS differences depated means chemotaxonomy.
