“…The growing interest on natural products that can be used as an alternative to synthetic chemicals in order to prevent and reduce the dangerous effects of microorganisms on historical artifacts (Mansour, 2013;Rakotonirainy and Lave`drine, 2005;Stupar et al, 2014;Casiglia et al, 2014aCasiglia et al, , 2014bCasiglia et al, 2015) prompted us, in the frame of our previous reports on Sicilian Thymus ssp. (De Feo et al, 2003;De Martino et al, 2009), to investigate on the chemical composition and anti-microbial properties against several microorganism, including Bacillus subtilis, Fusarium oxysporum and Aspergillus niger, species infesting historical material (Kamel et al, 2014;Gupta, 2013), of T. capitatus, collected on the northern coast of Sicily at three different vegetative stages.…”

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. These alterations produce deterioration of physical, chemical, mechanical and esthetic properties. Consequently, in this publication, we report the high antibacterial and antifungal activities of wild thyme essential oil, oil that can be used as an alternative natural tool in the fight against microorganisms affecting historical art crafts.Essential oil of the Thymus capitatus growing wild in northern Sicily has been extracted by hydrodistillation from aerial parts collected at different growth times. The constituents of the essential oil have been characterized by gas chromatography (GC) and GC-mass spectrometry.

“…Recently, also in the restore sector, the interest in biocompatible and eco-friendly solutions has increased. Many chemical products (quaternary ammonium compounds, chlorides, hypochlorites, and so on) are not used anymore and, when possible, a “green solution” is preferred [44,46,47,48,49,50]. There are less publications and application of natural eco-biocide for the stone artworks, but if these artefacts are outdoor, they are more steadily and repeatedly attacked by biodeteriogens [45,51,52].…”

Many chemicals used nowadays for the preservation of cultural heritage pose a risk to both human health and the environment. Thus, it is desirable to find new and eco-friendly biocides that can replace the synthetic ones. In this regard, plant essential oils represent effective alternatives to synthetic substances for the preservation of historical monuments. Thymbra capitata (syn. Thymus capitatus) is a medicinal and aromatic plant growing in the Mediterranean area and endowed with important pharmacological properties related to its essential oil. Among them, the antimicrobial ones make the T. capitata essential oil an ideal candidate for industrial applications; for instance, as biocide for the inhibition and elimination of biological patinas of cyanobacteria and green algae on historical monuments. In the present work, we studied the chemical composition of the essential oil from T. capitata growing in Malta by gas chromatography-mass spectrometry (GC/MS). The major volatile component is the phenolic monoterpene carvacrol (73.2%), which is capable of damaging the cytoplasmic membrane and to interfere both in the growth curve and in the invasive capacity, though the contribution of minor components γ-terpinene and p-cymene cannot be disregarded. For the oil application on the stone surface, Pickering emulsions systems were prepared with an essential oil/water 1:3 mass ratio stabilized with kaolinite at 4 mass% in the presence of Laponite®; this allowed to limit the fast volatility of the oil and guaranteed a better application and an easier removal from the artefacts attacked by biodeteriogens both indoor and outdoor. This formulation caused the elimination of biodeteriogens from treated surfaces without residuals or films on artworks surface, and the effect was retained up to four months.

“…These results are displayed in (Tables 2 and 3). -Pinene was detected in both M. laevis using the two different methods and M. spinosa [21], which had various biological activities as antioxidant, antifungal (C. albicans), antimalarial [22], antibacterial, antispasmodic and anti-inflammatory [23]. Furthermore, isobornyl acetate was found in the highest concentration in the volatile oil of leaves of M. laevis.…”

The current study was aimed to evaluate some parts of Moluccella laevis viz., phytochemical and antibacterial. Regarding to GC/MS of the saponifiable matters of petroleum ether fraction of total ethanolic extract of the aerial parts (TEE), the main recognized unsaturated fatty acids were methyl linolenate (25.58%) and methyl linoleate (15.87%). Whereas, the major saturated fatty acids were, palmitic (25.4%) followed by stearic acid (10.48). A comparative analysis of the volatile constituents of M. laevis flowers and leaves was performed by Head Space GC/MS. The volatile mixtures of both plant parts displayed comparable amounts of hydrocarbons and oxygenated compounds, with a noticeable greater contribution of the latter in the leaves.Besides, -pinene (40.84%), chrysanthenyl acetate (17.89%) and isobornyl acetate (10.64%), were identified as the major volatile components in the flowers. While, isobornyl acetate (35.09%) was characterized as the major constituent followed by, 2-methyl-4-butanolide (22.12%), 1-heptene oxide (7.47%) and benzoic acid, methyl ester (4.05%) of the volatile oil composition of the leaves. Moreover, this study included the antibacterial activity of TEE and its different fractions against Gram positive and negative bacteria. TEE exhibited MIC values of 326 476, and 541 µg/mL against E. coli, K. pneumonia and P. aeruginosa, respectively, while the aqueous fraction showed
