Mortality due to fungal infections has increased substantially, becoming a worldwide problem in public health. As a contribution to the discovery of new antifungal agents, the properties of the heartwood essential oils of two trees growing in New Caledonia, Callitris neocaledonica and C. sulcata (Cupressaceae) were investigated. The essential oils extracted by hydrodistillation were characterized by GC-FID and GC/MS analyses. From C. neocaledonica oil, 31 constituents were identified, representing 97.0% of the total oil composition, which was mainly constituted by oxygenated sesquiterpenes (88%). Among them, guaiol (1; 30.2%), bulnesol (2; 12.5%), α-eudesmol (3; 10.5%), β-eudesmol (4; 10.5%), γ-eudesmol (10.2%), and elemol (4.9%) predominated. The chemical composition of C. sulcata oil, from which 39 constituents were identified (96.8% of the total oil composition), showed some similarities with that of C. neocaledonica oil. The major constituents were also oxygenated sesquiterpenes, accounting for 78.5% of the oil, amongst them, mainly compounds 1 (16.1%), 3 and 4 (9.7% each), as well as 2 (7.4%). The antifungal activity of the oils against clinical isolates of four dermatophytic fungi (Trichophyton mentagrophytes, T. rubrum, Microsporum canis, and M. gypseum) and six yeasts (Candida albicans, C. parapsilosis, C. glabrata, C. krusei, Cryptococcus neoformans, and Cryptococcus gattii) was tested by determining minimum inhibitory concentrations (MICs) using the microdilution method. The best antifungal activities of the C. neocaledonica and C. sulcata oils were obtained against C. krusei (MICs of 3.9 and 0.975 μg/ml, resp.). These MIC values were similar to those of the reference drugs itraconazole and fluconazole (1.0 and 0.5 mg/ml, resp.). The oils were also subjected to a screening for their possible DPPH(.) (2,2-diphenyl-1-picrylhydrazyl) radical-scavenging activity. C. neocaledonica essential oil was more active than C. sulcata oil (93.3 vs. 32.2% DPPH(.) scavenged at 250 μg/ml).

The chemical composition of 45 essential oil samples isolated from the leaves of Polyalthia oliveri harvested in three Ivoirian forests was investigated by GC-FID (retention indices measured on two columns of different polarities), and by (13) C-NMR, following a method developed in our laboratory. In total, 41 components were identified. The content of the main components varied drastically from sample to sample: (E)-β-caryophyllene (1.2 - 50.8%), α-humulene (0.6 - 47.7%), isoguaiene (0 - 27.9%), alloaromadendrene (0 - 24.7%), germacrene B (0 - 18.3%), δ-cadinene (0.4 - 19.3%), and β-selinene (0.2 - 18.5%). The analysis of six oil samples selected in function of their chromatographic profiles is reported in detail. The 45 oil compositions were submitted to hierarchical cluster and principal components analysis, which allowed the distinction of three groups within the oil samples. The compositions of the oils from group I (15 samples) and II (12 samples) were dominated by (E)-β-caryophyllene and α-humulene, respectively. Oil samples of group III (18 samples) needed to be partitioned into four subgroups III.1-III.4 whose compositions were dominated by alloaromadenrene, isoguaiene, germacrene B, and δ-cadinene, respectively.

In grape berries (Vitis vinifera L.), sesquiterpenes are mainly accumulated as hydrocarbons in the epicuticular wax layer of grapes, whereas monoterpenes, which are predominantly present as alcohols, are glycosylated and are stored as glycosides in the vacuoles of grape berry cells. In this study, extensive analysis of grape berry hydrolysates by means of comprehensive two-dimensional gas chromatography–time-of-flight–mass spectrometry demonstrated that glycosylated sesquiterpene alcohols show very little structural diversity when compared to the sesquiterpene hydrocarbon fraction in the cuticle and are glycosylated to a rather low extent when compared to monoterpenols. Twenty-four enzymatically released terpenols were found in hydrolysates of the aromatic white wine variety Gewürztraminer (V. vinifera subsp. vinifera) after previous solid-phase extraction and headspace solid-phase microextraction. The detection of only three sesquiterpene alcohols, namely farnesol, nerolidol and drimenol, shows that most sesquiterpene hydrocarbons do not have a related hydroxylated structure in grapes. Nevertheless, the presence of the acyclic aglycone farnesol and nerolidol may be of importance for the wine aroma, since these structural isomers can be converted into numerous sesquiterpenes by nonenzymatic acid-catalyzed reactions during wine production. Grape-derived glycosidically bound sesquiterpene alcohols, therefore, represent, in addition to free sesquiterpene hydrocarbons, another pool of compounds that may influence the aroma profile of wines.
