Antimicrobial And Antioxidant Properties Of Artemisia L. Species From Western Anatolia, Şüra Baykan Erel, Gottfried Reznicek, Serdar Gökhan Şenol, Nefi̇se Ülkü Karabay Yavaşoğlu, Si̇bel Konyalioğlu, Ahmet Ulvi̇ Zeybek
Turkish Journal of Biology
Artemisia L. taxa (A. absinthium L., A. arborescens L., A. campestris L., A. scoparia Waldst. & Kit., A. santonicum L., and A. vulgaris L.) naturally distributed through western and southwestern Turkey were chosen as experimental materials in this study. Essential oils of the aerial parts of these Artemisia species were isolated by hydrodistillation and analyzed by gas chromatography-mass spectrometry. The major components were identified as sabinene in A. absinthium (17.56%), camphor in A. arborescens (33.39%), 1,2-dehydro acenaphthylene in A. campestris and A. scoparia (20.71% and 11.80%, respectively), and \alpha-thujone in A. vulgaris and A. santonicum (56.13% and 39.46%, respectively). Essential …
Antioxidant Activity And Luteolin Content Of Marchantia Polymorpha L., Alper Gökbulut, Basri̇ Satilmiş, Kadi̇r Batçioğlu, Barbaros Çeti̇n, Engi̇n Şarer
Antioxidant Activity And Luteolin Content Of Marchantia Polymorpha L., Alper Gökbulut, Basri̇ Satilmiş, Kadi̇r Batçioğlu, Barbaros Çeti̇n, Engi̇n Şarer
Turkish Journal of Biology
Antioxidant activity of the methanol and ethyl acetate extracts of Marchantia polymorpha L., which grows naturally in Turkey, was tested by DPPH and ABTS methods. According to the applied methods, both extracts exhibited moderate activity. Some phenolic compounds that could be responsible for the activity were investigated by RP-HPLC, qualitatively and quantitatively, in the methanolic extract of liverwort. While caffeic acid, chlorogenic acid, rutin, myricetin, quercetin, and kaempferol were not found in the extract, luteolin as the liable antioxidant agent was determined as 0.0052 ± 0.0002% among the investigated compounds.
Antihyperglycemic, Antioxidant And Cytotoxic Activities Of Alocasia Macrorrhizos (Linn.) Rhizomes Extract, Md Masudur Rahman, Md. Aslam Hossain, Saiful Alam Siddique, Kaishar Parvej Biplab, Md. Helal Uddin
Antihyperglycemic, Antioxidant And Cytotoxic Activities Of Alocasia Macrorrhizos (Linn.) Rhizomes Extract, Md Masudur Rahman, Md. Aslam Hossain, Saiful Alam Siddique, Kaishar Parvej Biplab, Md. Helal Uddin
Turkish Journal of Biology
Alocasia macrorrhizos (L.) (Araceae), a coarse and erect plant that is widely cultivated to be eaten as a vegetable throughout Bangladesh, has been reported to possess a number of medicinal properties. The antihyperglycemic, antioxidant, and cytotoxic effects of the methanol extract of A. macrorrhizos rhizomes were investigated. The extract was given at a single dose (250 and 500 mg/kg) in alloxan-induced hyperglycemic mice. The extract at 500 mg/kg produced a significant (P < 0.05) decrease in the blood glucose level (55.49%) at 8 h of treatment when compared with the control and was comparable with the reference drug, metformin. The extract was also subjected to antioxidant potentiality and brine shrimp lethality bioassays. The IC_{50} value of the extract was 693.0 \mug/mL and the LC_{50} was 188.14 \mug/mL.
Assessment Of Antioxidant, Antibacterial, Antimycobacterial, And Antifungal Activities Of Some Plants Used As Folk Remedies In Turkey Against Dermatophytes And Yeast-Like Fungi, Di̇dem Deli̇orman Orhan, Berri̇n Özçeli̇k, Sanem Hoşbaş, Meci̇t Vural
Assessment Of Antioxidant, Antibacterial, Antimycobacterial, And Antifungal Activities Of Some Plants Used As Folk Remedies In Turkey Against Dermatophytes And Yeast-Like Fungi, Di̇dem Deli̇orman Orhan, Berri̇n Özçeli̇k, Sanem Hoşbaş, Meci̇t Vural
Turkish Journal of Biology
Twenty-seven aqueous extracts obtained from 21 plants used in the treatment of respiratory tract infections as folk remedies in Turkey were investigated for their relative total phenolic contents and antioxidant, antibacterial, antimycobacterial, and antifungal activities. Antibacterial and antifungal activities against dermatophytes and yeast-like fungi were determined using the microdilution method. Antibacterial activity of all extracts was more pronounced against gram-positive bacteria than against gram-negative bacteria. These extracts also exhibited higher antifungal activity against Candida krusei than ketaconazole. Six extracts displayed antidermatophytic activity against Epidermophyton floccosum, while only 3 extracts were highly active against Trichophyton rubrum. The extracts showed strong activity …
Antioxidant And Acetylcholinesterase Inhibitory Potential Of Arnica Montana Cultivated In Bulgaria, Dimitrina Zheleva Dimitrova, Vessela Balabanova
Antioxidant And Acetylcholinesterase Inhibitory Potential Of Arnica Montana Cultivated In Bulgaria, Dimitrina Zheleva Dimitrova, Vessela Balabanova
Turkish Journal of Biology
The antioxidant and acetylcholinesterase inhibitory potential of methanol extract from Arnica montana cultivated in Bulgaria was evaluated. For the determination of antioxidant activity 1,1-diphenyl-2-picrylhydrazyl (DPPH), 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) di-ammonium salt (ABTS) free radicals, and ferric reducing antioxidant power (FRAP) assay were used. Modified Ellman's colorimetric method was used for quantitative assessment of acetylcholinesterase inhibition potential. Butylated hydroxytoluene (BHT) and galantamine hydrobromide were used as positive controls, respectively. In addition, total polyphenols and tannins, flavonoids, hydroxycinnamic derivatives, and sesquiterpene lactones were determined using Folin-Ciocalteu reagent, AlCl_3, Na_2MoO_4, and m-dinitrobenzene, respectively. The results demonstrated that Arnica extract has strong antioxidant activity and moderate …
