Chemical Composition of the Essential Oils of Three Endemic Species of Anthemis Sect. Hiorthia (DC.) R.Fern. Growing Wild in Sicily and Chemotaxonomic Volatile Markers of the Genus Anthemis L.: An Update

Abstract

The chemical composition of the essential oils isolated from the aerial parts of Anthemis pignattiorum Guarino, Raimondo & Domina and A. ismelia Lojac. and the aerial parts and flowers of Anthemis cupaniana Tod. ex Nyman, three endemic Sicilian species belonging to the section Hiorthia, was determined by GC-FID and GC/MS analyses. (Z)-Muurola-4(14),5-diene (27.3%) was recognized as the main constituent of the A. pignattiorum essential oil, together with isospathulenol (10.6%), sabinene (7.7%), and artemisyl acetate (6.8%), while in the oil obtained from the aerial parts of A. ismelia, geranyl propionate (8.8%), bornyl acetate (7.9%), β-thujone (7.8%), neryl propionate (6.5%), and τ-muurolol (6.5%) prevailed. α-Pinene was the main compound of both the aerial part and flower oils of A. cupaniana (18.4 and 13.2%, resp.). Also noteworthy are the considerable amounts of artemisyl acetate (12.7%) and β-thujone (11.8%) found in the oil from the aerial parts and those of tricosane (9.8%) and sabinene (7.6%) evidenced in the flower oil. Furthermore, an update on the main compounds identified in the essential oils of all the Anthemis taxa studied so far was presented, and cluster analyses were carried out, to compare the essential oils of these taxa.

Chemical composition of essential oils extracted from six Murraya species and their repellent activity against Tribolium castaneum

“…The components were identified by comparing their mass spectra and calculating RI values with those in NIST 05 and Wiley 275 libraries, and those published in the literatures (Adam, 2001;Cannon et al, 2015;Chang and Kim, 2009;Li et al, 2010;Lin et al, 2012;Maggio et al, 2014;Yu et al, 2014). Relative percentages of each component in the essential oils were obtained by averaging the GC-FID peak area% reports.…”

Chemical Composition and Antibacterial Activity of Essential Oils from Ferula L. Species against Methicillin-Resistant Staphylococcus aureus

“…The chemical composition of 8 EOs from F. ovina and 4 EOs from F. akitschkensis is summarized in Table 1 , where the identified compounds are listed in order of their elution. In addition, the relative retention index (RRI exp ) values obtained for the detected constituents are included for comparison with those values previously reported (RRI lit ) for these compounds [ 37 , 38 , 39 , 40 , 41 , 42 , 43 , 44 , 45 , 46 , 47 , 48 , 49 , 50 , 51 , 52 , 53 ].…”

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

“…Consequently, in this study, as a continuation of researches on Sicilian species of Asteraceae (Acquaviva et al 2012;Formisano et al 2012;Maggio et al 2014;Maggio, Venditti, et al 2015), we report the chemical composition and the antibacterial activity against several microorganisms, including Bacillus cereus, Bacillus subtilis and Staphylococcus ssp., species infesting historical art craft (Kamel et al 2014), of the essential oils from aerial parts of P. vulgaris var. graeca (Sch.-Bip.)…”
