Influence of harvesting time on composition of the essential oil of Thymus capitatus (L.) Hoffmanns. & Link. growing wild in northern Sicily and its activity on microorganisms affecting historical art crafts

One of the main factors affecting historical art crafts material is the biodeterioration performed by bacteria and fungi, in archives, museums or private collections. Several microorganisms cause degradation to the natural organic material such as fibers, woods, and dyes as well as to stone objects....

The constituents of the essential oil have been characterized by gas chromatography (GC) and GC–mass spectrometry.Fifty-five compounds have been identified. Essential oils were characterized by a high content of carvacrol (81.2–14.2%), γ-terpinene (34.4–2.6%) and p-cymene (22.8–5.0%) of the total oil content. Essential oil yield and composition vary throughout the vegetation time of the plant. The best time to harvest this species of thyme, for phenol content, is during or immediately before the full bloom. The related oils (Tc2 and Tc3) showed a good antibacterial activity against Bacillus subtilis and Staphylococcus epidermidis and excellent antifungal properties against Fusarium oxysporum and Aspergillus niger.
