Lc-Hrms Profiling and Antidiabetic, Anticholinergic, and Antioxidant Activities of Aerial Parts of Kinkor (Ferulago Stellata)

Abstract

Kinkor (Ferulago stellata) is Turkish medicinal plant species and used in folk medicine against some diseases. As far as we know, the data are not available on the biological activities and chemical composition of this medicinal plant. In this study, the phytochemical composition; some metabolic enzyme inhibition; and antidiabetic, anticholinergic, and antioxidant activities of this plant were assessed. In order to evaluate the antioxidant activity of evaporated ethanolic extract (EEFS) and lyophilized water extract (WEFS) of kinkor (Ferulago stellata), some putative antioxidant methods such as DPPHGreek ano teleia scavenging activity, ABTS(center dot+) scavenging activity, ferric ions (Fe3+) reduction method, cupric ions (Cu2+) reducing capacity, and ferrous ions (Fe2+)-binding activities were separately performed. Furthermore, ascorbic acid, BHT, and alpha-tocopherol were used as the standard compounds. Additionally, the main phenolic compounds that are responsible for antioxidant abilities of ethanol and water extracts of kinkor (Ferulago stellata) were determined by liquid chromatography-high-resolution mass spectrometry (LC-HRMS). Ethanol and water extracts of kinkor (Ferulago stellata) demonstrated effective antioxidant abilities when compared to standards. Moreover, ethanol extract of kinkor (Ferulago stellata) demonstrated IC50 values of 1.772 mu g/mL against acetylcholinesterase (AChE), 33.56 +/- 2.96 mu g/mL against alpha-glycosidase, and 0.639 mu g/mL against alpha-amylase enzyme respectively.
