Abstract
Objective: The objective of present study was to evaluate the antibacterial and antioxidant activities of essential oils from Thymus vulgaris, Thymus kotschyanus, Ziziphora tenuior and Ziziphora clinopodioides. Methods: The antioxidant potency of essential oils was determined by 2,2-diphenyl-1- picrylhydrazyl and reducing power assays. Total phenolic contents of essential oils were determined using the Folin-Ciocalteu reagent assay. The antibacterial activity of essential oils was evaluated using agar disc diffusion and minimum inhibitory concentration (MIC) methods. Results: The essential oils of Ziziphora clinopodioides and Thymus vulgaris showed the highest antioxidant activity. The essential oils of Thymus vulgaris showed the strongest antibacterial activity with the widest inhibition zone and the lowest MIC value (2.5 μl/ml). The essential oils of Thymus vulgaris had the highest concentration of total phenolics (116.5
期刊介绍：
Turkish Journal of Biochemistry (TJB), official journal of Turkish Biochemical Society, is issued electronically every 2 months. The main aim of the journal is to support the research and publishing culture by ensuring that every published manuscript has an added value and thus providing international acceptance of the “readability” of the manuscripts published in the journal.
