2016

Hydrodistillation of the flowers (BpFl) of and fruits (BpFr) of Bupleurum fontanesii Guss. ex Caruel gave two oils that were analyzed by GC and GC-MS. The main components were α-elemol (16.7%), caryophyllene oxide (16.4%) and heptacosane (15.9%) in BpFl, and spathulenol (16.8%), caryophylladienol I (13.2%) and α-elemol (12.8%) in BpFr. A good antimicrobial activity against several microorganisms, including Bacillus subtilis, Staphylococcus aureus, Fusarium oxysporum and Aspergillus niger, all infesting historical art craft, was also determined.

Volatile constituents of Dianthus rupicola Biv. from Sicily: activity against microorganisms affecting cellulosic objects.

2014

Dianthus rupicola Biv. (cliffs carnation) is a camephytic, suffruticous, perennial plant growing up to 40 cm high. The plant is widespread in Sicily and neighbouring islands (Egadi, Lampedusa, Lipari) and in some areas of southern Italy. GC and GC-MS analyses of the essential oil distilled from the flowers showed the presence of 66 components. Its composition is characterised by the high content of thymol and carvacrol derivatives. A good antibacterial activity against Bacillus cereus and Bacillussubtilis, both infesting cellulosic historical material, was shown, whereas the antioxidant capacity was determined to be quite poor.

Kundmannia sicula (L.) DC: a rich source of germacrene D

2017

AbstractObjective: Kundmannia sicula is an herbaceous plant belonging to the family Apiaceae and is distributed in the Mediterranean coastal areas where it occurs in arid places. In this work, we have analysed the essential oil distilled from the aerial parts of K. sicula from Sicily (Italy) and its biological activity. Methods: GC-MS was used to analyze the chemical composition, whereas its antioxidant capacity and cytotoxicity on three human tumour cells (A375, MDA MB-231 and HCT 116) were evaluated by DPPH, ABTS, FRAP and MTT methods, respectively. Result: The essential oil resulted very rich of the sesquiterpene hydrocarbon germacrene D (81.2%). Moreover, the K. sicula oil displayed rel…

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…
