Volatile Constituents of the Aerial Parts of Pulicaria sicula (L.) Moris Growing Wild in Sicily: Chemotaxonomic Volatile Markers of the Genus PulicariaGaertn.

Abstract

The chemical composition of the essential oil isolated from the aerial parts of Pulicaria sicula (L.) Moris was characterized by GC-FID and GC/MS analyses. The oil was particularly rich in oxygenated terpenoids. Among the oxygenated monoterpenes (content of 44.5%), the most abundant were borneol (23.7%), bornyl acetate (6.5%), and isothymol isobutyrate (6.2%). Caryophyllene oxide (10.2%), caryophylladienol I (4.3%), and caryophylla-3,8(13)-dien-5β-ol (4.4%) were identified as the main constituents among the oxygenated sesquiterpenes. Furthermore, a complete literature review on the composition of the essential oils of all the Pulicaria taxa studied so far was performed and a principal component analysis (PCA) was carried out.

“…(wild tea) [29,30], P. jaubertii [16], P. mauritanica (Ifenzi oudaden) [31,32], P. odora (L.) Rchb. (Mediterranean fleabane) [18], P. sicula (L.) Moris (fleabane) [33], P. stephanocarpa Balf.f. (derbeb) [17], P. undulata [34][35][36][37], and P. vulgaris Gaertn.…”

(−)-β-Caryophyllene, a CB2 Receptor-Selective Phytocannabinoid, Suppresses Motor Paralysis and Neuroinflammation in a Murine Model of Multiple Sclerosis

“…(−)-β-caryophyllene (BCP), a functional non-psychoactive CB2 receptor agonist [12,13,14], is found in, for example, plant-derived oleoresins, essential oils, solutes, distillates, extracts, fermentations, infusions, and leachates, from several plants [15,16,17,18,19,20,21,22,23,24,25]. Furthermore, BCP showed analgesic, anti-inflammatory, neuroprotective, anti-depressive, anxiolytic, and anti-nephrotoxicity effects [12,13,26,27,28,29,30,31].…”

Chemical composition of the essential oil fromPulicaria vulgarisvar.graeca(Sch.-Bip.) Fiori (Asteraceae) growing wild in Sicily and its antimicrobial activity

“…for 21.7%), shows a complete different chemical profile of the two taxa. Although the huge presence of thymol derivatives as in P.v., with the exception of P. arabica collected in Tunisia (Abed et al 2010), is not a common feature in Pulicaria genus (Maggio, Riccobono, et al 2015), the occurrence of carvotanacetone has been reported in several taxa such as P. jaubertii collected in S. Arabia (98.6%) (Fawzy et al 2013 (Algabr et al 2012) and P. arabica collected in Tunisia (3.5%) (Abed et al 2010), whereas b-caryophyllene, the second most abundant compound of P.v.g., is present in good quantity in P. dysenterica collected in Greece (Basta et al 2007) and P. stephanocarpa collected in Soqotra (Ali, Crouch, et al 2012). Finally, geranyl propionate (8.2% in P.v.g.…”

“…graeca with those reported for the essential oil of P. vulgaris Gaertner (P.v.) (Sharifi-Rad et al 2014) and of all the other taxa of Pulicaria studied so far, recently reviewed (Maggio, Riccobono, et al 2015), shows some interesting points.…”
