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.

This study was geared towards assessing the possible antioxidant, enzyme inhibitory, and cytotoxic activities of ethyl acetate, methanol, and water extracts of Sideritis ozturkii Aytaç & Aksoy. The phytochemical profiles of the studied extracts were characterised by HPLC-MS/MS. The methanol extract, rich in phenolics (78.04 mg gallic acid equivalent/g), exhibited the strongest antioxidant activities. However, the ethyl acetate extract was the most active extract in the enzyme inhibitory assays. The water extract of S. ozturkii (1 mg/ml, 48 h incubation) slightly inhibited (22%) growth of human breast cancer cell line (MDA-MB-231 cells). On the other hand, the ethyl acetate and methanol extracts showed strong inhibition (98% and 97%, respectively) of MDA-MB-231 cells and caused apoptotic cell death. Scientific data generated from this study further appraises the multiple biological activities of plants belonging to the Sideritis genus. In addition, preliminary evidence gathered from the current investigation advocates for further studies geared towards the preparation of therapeutic formulations from S. ozturkii.
