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

Abstract

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.

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

“…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.…”

Diethyl‐Ether Flower Washings of Dianthus cruentusGriseb. (Caryophyllaceae): Derivatization Reactions Leading to the Identification of New Wax Constituents

“…The genus Dianthus L. (Caryophyllaceae) comprises over 300 species of herbaceous plants that are spread over a vast area, having a diversity hot-spot in the Mediterranean region. [1,2] Species of this genus are esteemed as ornamental plants that were either cultivated and collected from wild populations for more than 2000 years primarily due to the vibrant coloration (ranging from white to deep purple) and scent of their flowers. [3] According to the latest data, published in the second edition of the 'Flora of Serbia', the genus Dianthus contains 36 species; [4] however, plant species of the genus Dianthus originating from Serbia have never been previously investigated phytochemically.…”

“…[3] Species of this genus have a long history of use in folk medicine. For example, Dianthus carthusianorum was used by monks to relieve pain and rheumatism [2] and flowers of D. caryophyllus have been used in ethno medicine of northern Iraq for the treatment of gastrointestinal disorders, wounds and throat infections. [5] Secondary metabolites of D. caryophyllus flower extract and essential oil displayed a repellent effect against ticks (Ixodes ricinus) and mosquitoes (Aedes aegypti and Culex pipiens).…”
