Effects of Cuts and Different Phenological Stages on Antibacterial and Antioxidant Activities and Chemical Attributes of Garden Thyme (Thymus vulgaris L.) Essential Oil

Garden thyme is an aromatic plant with various applications in the pharmaceutical, food, and hygienic-cosmetic industries around world. In this research, field-cultivated plants were harvested two cuts three consecutive stages (pre-flowering, flowering, post-flowering). The essential oil percentage compositions identified samples. antibacterial activity of was measured against Escherichia coli Staphylococcus aureus. antioxidant activity, total phenol flavonoid contents, chain-breaking IC50 recorded. highest (2.56%) obtained from pre-flowering stage. results GC/MS revealed that p-cymene, γ-terpinene, thymol, carvacrol most important constituents studied oil. lowest recorded by second cut at E. S. aureus during flowering stage first stage, respectively. MIC 15.75 μg mL-1 related to had (16.64 mg GAE g-1 DM) contents (2.88 QE (IC50 = 134.05 mL-1) observed It can be said phenological affect activities, as well its chemical characteristics.
