Turkish Journal of Chemistry
In the present work, essential oil and fatty acids and extracts obtained from aerial parts of Phlomis linearis Boiss. & Bal. were investigated for chemical composition and biological activities. The phytochemical analyses were conducted with gas chromatographymass spectrometry/flame ionisation detector (GC-MS/FID) and liquid chromatography-mass spectromtetry (LC-MS/MS) techniques. The extracts and essential oil were studied for α-amylase and acetylcholinesterase activities with two different spectrophotometric methods. Antimicrobial activities of the extracts were investigated by microdilution. The extracts were evaluated in vitro for cytotoxic effects against cancer and normal cell lines by MTT assay. The essential oil (EO) contained α-pinene (12.5%) and β-caryophyllene …
Chemical Composition And Biological Activities Of Essential Oils Of Two New Chemotypes Of Glebionis Cass., Hüseyi̇n Servi̇
Chemical Composition And Biological Activities Of Essential Oils Of Two New Chemotypes Of Glebionis Cass., Hüseyi̇n Servi̇
Turkish Journal of Chemistry
This paper includes the result of the first study of the chemical composition, antioxidant, antiinflammatory, and antidiabetic activities of the essential oils of Glebionis coronaria (L.) Cass. ex Spach and Glebionis segetum (L.) Fourr. from Turkey. In the current study, nine and twenty-eight constituents were determined in the essential oils of aerial parts of G. coronaria (GCE) (92.1%) and G. segetum (GSE) (90.0%), respectively. The main components were capillin (65.9%) in GCE, capillene (53.4%) in GSE. The essential oil compositions were evaluated and compared with previous researches. In the current study, the plants are classified as chemotypes of Glebionis species. …
Characterization Of Extracts From Papaver Rhoeas And Potential Valorization Of Theseextracts In Dyeing Applications, Mohand Ouidir Boussoum, Rachida Ouldmokhtar, Abdelkader Ali Nehari, Beatrice George
Characterization Of Extracts From Papaver Rhoeas And Potential Valorization Of Theseextracts In Dyeing Applications, Mohand Ouidir Boussoum, Rachida Ouldmokhtar, Abdelkader Ali Nehari, Beatrice George
Turkish Journal of Chemistry
The aim of our work is to study the dyeing properties of extracts from natural sources such as Papaver rhoeas by modifying the conditions of the dyeing process, choosing other substrates that could be pretreated by innovative and environmentally friendly processes. The results obtained show a fairly high fixation of the extracts on the natural and artificial fibers. The use of mordants allowed the dye to be better fixed on the dyed fibers and to give several shades to the fabric. The rate of essential oil contained in Papaver rhoeas was considered important by the Clevenger process. Screening of extractive …

Phenolic Compounds, Essential Oil Composition, And Antioxidant Activity Of Angelica Pur-Purascens (Avé-Lall.) Gill, Semra Alkan Türkuçar, Ayça Aktaş Karaçeli̇k, Mustafa Karaköse
Turkish Journal of Chemistry
In this study, methanol extracts (MEs) and essential oil (EO) of Angelica purpurascens (Avé-Lall.) Gill obtained from different parts (root, stem, leaf, and seed) were evaluated in terms of antioxidant activity, total phenolics, compositions of phenolic compound, and essential oil with the methods of 2,2-azino-bis(3ethylbenzo-thiazoline-6-sulfonic acid (ABTS•+), 2,2-diphenyl-1-picrylhydrazil (DPPH•) radical scavenging activities, and ferric reducing/antioxidant power (FRAP), the Folin?Ciocalteu, liquid chromatography- tandem mass spectrometry (LC-MS/MS), and gas chromatography-mass spectrometry (GC-MS), respectively. The root extract of A. Purpurascens exhibited the highest ABTS•+, DPPH•, and FRAP activities (IC50: 0.05 ± 0.0001 mg/mL, IC50: 0.06 ± 0.002 mg/mL, 821.04 ± 15.96 μM TEAC …
Gc-Ms Analyses And Bioactivities Of Essential Oil Obtained From The Roots Ofchrysopogon Zizanioides (L.) Roberty Cultivated In Giresun, Turkey, Derya Efe, Mustafa Karaköse, Ayça Aktaş Karaçeli̇k, Bengü Ertan, Mehmet Emi̇n Şeker

Turkish Journal of Chemistry
The essential oils (EOs) constituents have trade importance due to their bioactivities. In this research, the essential oil of the roots of Chrysopogon zizanioides (L.) Roberty cultivated in Giresun was obtained by hydrodistillation. Then, the chemical composition and biological activities of Chrysopogon zizanioides root essential oil (CEO) were studied. Thirty compounds were identified by gas chromatography-mass spectrometry (GC-MS) and the major compounds were determined as isobutyl-angelate (11.15%), α-muurolene (10.56%), α-cedrene (8.42%), α-patchoulene (8.10%), and ethylene brassylate (7.49%). The antimicrobial effect of CEO was investigated against pathogenic bacteria and fungus. Minimal inhibition concentration (MIC) was determined 31.25 μg/mL against C. albicans …
