Background: Thymus kotschyanus Boiss., commonly known as thyme, is a small semi-shrub valued for its aromatic and medicinal properties. Found throughout the Middle East and the Caucasus, it adapts to various ecological conditions and is rich in biologically active compounds, including essential oils, flavonoids, and phenolic acids. Its diverse chemical profile has made it a focus of pharmacological research for its antimicrobial, antioxidant, and anti-inflammatory effects, highlighting its potential therapeutic applications.
Objective: The study aimed to investigate the bioactive compounds in wild T. kotschyanus Boiss. plants grown under diverse ecological conditions, with an emphasis on how these compounds change in response to varying environmental contexts.
Materials and Methods: The chemical composition of Thymus kotschyanus Boiss. was investigated during its flowering phenophase. Aerial parts of plants were collected from the Tavush (40°880518N, 45°427958E) and Kotayk (40°17’56"N, 44°33’15"E) regions in Armenia between 2021 and 2023. The study focused on analyzing ash and moisture content, phytochemical screening, and mineral content.
Results: The ethanolic extracts of Thymus kotschyanus Boiss from both regions contained a diverse array of bioactive compounds, including coumarins, flavonoids, alkaloids, tannins, phenols, carbohydrates, proteins, and saponins. Plants from the Tavush region exhibited a moisture content 1.83% higher than those from the Kotayk region, reflecting a 36.1% increase. Similarly, the ash content was 1.3% higher in Tavush plants, resulting in a 17.1% increase compared to Kotayk plants. Analysis of macro- and microminerals revealed that potassium was the most abundant macromineral, followed by calcium, magnesium, phosphorus, and sodium. Among the microminerals, iron had the highest concentration, followed by zinc and copper.
Conclusion: The study demonstrated significant differences in the biologically active compounds, mineral composition, moisture, and ash content of T. kotschyanus Boiss. from different ecological zones in Armenia. Plants from the Tavush region exhibited higher moisture and ash content, as well as elevated levels of vitamins A and C, phenolic content, and essential minerals such as calcium, magnesium, sodium, potassium, and phosphorus, compared to those from the Kotayk region. These findings underscore the impact of environmental conditions on the quality and composition of T. kotschyanus Boiss., highlighting its potential as a valuable source of biologically active compounds and essential minerals.
