Toplam 130 atıf DOI
The antioxidant and enzyme inhibitory potential of different solvent extracts (petroleum ether, ethyl acetate, methanol and water) from Sideritis galatica were evaluated. Cholinesterase, α-amylase and α-glucosidase inhibitory activities of the extracts were tested by microtiter plate assays. Antioxidant abilities were tested using free radical scavenging (DPPH (1,1-diphenyl-2-picrylhydrazyl), ABTS (2,2'-azino-bis(3-ethylbenzothiazoline)-6-sulfonic acid) and NO), reducing power (FRAP (ferric reducing antioxidant power) and CUPRAC (cupric reducing antioxidant capacity)), total antioxidant capacity and chelating assays. Methanol and water extracts showed higher phenolic content, DPPH and ABTS scavenging activity and reducing power activities, while the petroleum ether and ethyl acetate extract had the highest inhibition abilities on the enzymes. 18 phenolic components in these extracts were detected by using high performance liquid chromatography-diode array detector (HPLC-DAD). Results obtained in this work indicate that S. galatica may be useful as a source of natural agents for the management of oxidative process, Alzheimer's disease and type II diabetes.

Havuzumuzda 73 atıf almış
Morina persica L. has weak rosy smell flowers that together with aerial parts are infused or decocted and used as a functional tea. It is a representative of the Anatolian traditional medicine and is used for the treatment of cold. Biological and chemical fingerprints of different extracts (methanolic, acetone and water) of M. persica were investigated. Antioxidant, enzyme inhibitory, antimicrobial, cytotoxic and mutagenic/antimutagenic effects were evaluated for biological profiling. Rutin, chlorogenic and rosmarinic acids were detected as dominant compounds. Generally, the methanolic and acetone extracts had strong antioxidant, enzyme inhibitory, antimicrobial and antimutagenic effects. Additionally, all extracts showed remarkable inhibitory effects on HeLa cells at 100 μg/mL. Furthermore, possible interactions between rutin, the dominant phenolic compound in M. persica and the tested enzymes were assessed by molecular docking. Results indicate that M. persica could be considered as a natural source of high-valued functional ingredients for further use in healthful formulations.
