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 …

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.
