In this study, the effects of seven distinct were assessed in two harvesting seasons (spring and autumn) on the essential oil (EO) content, total phenolic content (TPC), total flavonoid content (TFC), antioxidant activity, and volatile compounds of thyme ( Thymus vulgaris L.). The drying methods tested included sun-drying, shade-drying, freeze-drying (FD), oven drying at 40 °C (OV40) and 70 °C (OV70), and microwave 360 W (MW360) and 720 W (MW720). The analysis of essential oils facilitated the identification of numerous compounds, 18 of which accounted for approximately 64.94% to 67.84% of the total thyme EO compounds. Six significant compounds were investigated, including thymol, p -cymene, γ-terpinene, carvacrol, linalool, and borneol. The results demonstrated that the thyme samples harvested in spring possessed higher amounts of γ-terpinene, thymol, carvacrol, EO content, and TFC, while samples harvested in autumn exhibited the highest amounts of borneol, p -cymene, TPC, and higher antioxidant activity. ...
