| Abstract | The chemical compositions of 25 Corsican Limbarda crithmoides ssp. longifolia essential oils were investigated for the first time using GC-FID, GC/MS, and NMR analyses. Altogether, 65 compounds were identified, accounting for 90.0-99.3% of the total oil compositions. The main components were p-cymene (1; 15.1-34.6%), 3-methoxy-p-cymenene (4; 11.8-28.5%), 2,5-dimethoxy-p-cymenene (5; 5.9-16.4%), thymol methyl ether (6; 1.3-14.9%), -phellandrene (2; 0.9-11.9%), and -pinene (3; 0.2-13.4%). The chemical variability of the Corsican oil samples was studied using multivariate statistical analysis, which allowed the discrimination of two main clusters. A direct correlation between the water salinities of the plant locations and the chemical compositions of the L. crithmoides essential oils was evidenced. Indeed, essential oils rich in 1 (30.4-34.6%) were found in samples growing in the wetlands of the southern oriental coast, which exhibit high salinity levels (24.4 +/- 0.2-33.9 +/- 0.2ppt), and essential oils with lower contents of 1 (15.1-27.3%) were isolated form samples growing in the wetlands of northern Corsica, which exhibit lower salinity levels (10.90 +/- 0.20-15.47 +/- 0.15ppt). The antioxidant potential of L. crithmoides essential oil was also investigated, by assessing the DPPH.- and ABTS(.+)-scavenging activities and the reducing power of ferric ions, and was found to be interesting. Moreover, using bioassay-guided fractionation of the essential oil, a higher antioxidant activity was obtained for the oxygenated fraction and both ester and alcohol subfractions. |
