Oil Extract

The strongly antiseptic and antifungal activities of thyme is mainly due to the presence of phenolic compounds, thymol and carvacrol. Thyme extracts essential oil, extract obtained using 70% ethanol and extract obtained by supercritical fluid extraction (SFE) using carbon dioxide, were incorporated in the most useful form of pharmaceutical products - tablets. The work is concerned with the characterisation of the obtained tablets containing thyme extracts.
