Phytochemical, ecological and antioxidant evaluation of wild Sicilian thyme: Thymbra capitata (L.) Cav.
2016
In a broad survey conducted throughout the Sicily region, 45 different sites were identified where thyme grows wild. All the biotypes collected were classified as Thymbra capitata (L.) Cav. (syn. Thymus capitatus (L.) Hoffmanns. & Link). Cluster analysis based on the main morphological characteristics of the plant led to the division of the biotypes into 3 major groups. All samples were analyzed for their secondary phytochemical metabolites identified in the extracts and the essential oils. LC-UV-DAD/ESI-MS and GC-FID/GC-MS have been applied to characterize the extracts and the essential oils, respectively. In the extracts, 15 flavonoid derivatives with taxifolin-di-O-glucoside and thymusin…
The Essential Oil of Thymbra capitata and its Application as A Biocide on Stone and Derived Surfaces
2019
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
Propagation of three thymus species by stem cuttings
2006
Many herbs native to the Mediterranean region are grown for ornamental purposes and represent an important segment of the bedding plant industry. Although the majority of Thymus species are used as officinal plants, some of them are also used as ornamental bedding plants to provide aesthetic enhancement of public and private garden beds, porches, patios, balconies. The aim of this research was to study the vegetative propagation of T. capitatus, T. serpyllum and T. vulgaris. To verify the rooting response to exogenous application of auxin, softwood cuttings were either treated with a 500 ppm 1H-indol-3-butyric acid (IBA) solution, or not treated (control). Propagation was performed in an un…
Flexible mats as promising antimicrobial systems via integration of Thymus capitatus (L.) essential oil into PLA
2020
Aim: To develop electrospun mats loaded with Thymus capitatus (L.) essential oil ( ThymEO) and to study their morpho-mechanical and antimicrobial properties. Materials & methods: Poly(lactic acid) (PLA) mats containing ThymEO were prepared by electrospinning. The effect of ThymEO on the morpho-mechanical properties of fibers was assayed by scanning electron microscopy and dynamometer measurements. The antimicrobial activity of ThymEO delivered either in liquid or vapor phase was assessed through killing curves and invert Petri dishes method. The cytotoxicity was also investigated. Results: The mechanical properties were enhanced by integrating ThymEO into PLA. Both liquid and vapors of…
Influence of harvesting time on composition of the essential oil of Thymus capitatus (L.) Hoffmanns. & Link. growing wild in northern Sicily and its …
2019
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 no…
