Correction: Foliar Essential Oil Glands of Eucalyptus Subgenus Eucalyptus (Myrtaceae) Are a Rich Source of Flavonoids and Related Non-Volatile Constituents

Protium aracouchini (Aubl.) Marchand [sin Icica aracouchini Aubl.], which occurs in the Adolpho Ducke Forest Reserve, in the Brazilian Amazon, was evaluated for the presence of galls, for resin exudation and the composition of the essential oils from the aerial parts and the resin. The experiment to stimulate the exudation of resin from the trunk was conducted using a 2-chloroethylphosphonic acid solution. The resin produced after 40 days and the aerial parts had their essential oils extracted in a Clevenger apparatus and the volatile chemical constituents were analyzed using GC/MS. The non-oxygenated sesquiterpenes α-copaene (21.15%) and α-gurjunene (13.69%), in addition to the oxygenated sesquiterpene spathulenol (10.32%), were detected as the majority constituents of the essential oil of the leaves, and a concentration similar to that of α-gurjunene was found in the branches (13.28%). The resin essential oil showed a high concentration of hydrocarbon monoterpenes (76.49%) with a predominance of α-pinene (17.57%) and limonene (46.11%). Four gall morphotypes were found associated with this species. The present study reports for the first time information on the volatile constituents and the resinous potential of P. aracouchini, and registers the morphotypes of the galls that help in the taxonomy of the species.

Salvia leucantha Cav. (Lamiaceae), native to Mexico, is found in Venezuela in parks and gardens. Hydrodistillation of the fresh leaves of this plant yielded 0.05% of essential oil. GC and GC/MS analyses permitted the identification of 30 compounds, which made up 95.9% of the oil. The most abundant constituents were bornyl acetate (24.1%), β-gurjunene (14.8%), β-caryophyllene (14.1%), dillapiol (11.0%) and bicyclogermacrene (8.9%).

The composition of the steam volatile constituents of leaf, fruit and bark of Neolitsea pallens (D. Don) syn. Litsea umbrosa var. consimilis Nees Hook f. syn. L. consimilis Nees were analyzed by GC, GC-MS and NMR spectroscopy. The major constituents of the leaf oil were furanogermenone (30.6%), β-caryophyllene (19.3%) and germacrene D (12.7%), while oxygenated sesquiterpenoids (83.6%) constitute the major proportion of the bark oil, which is dominated by furanogermenone (59.1%), germacrone (9.3%), 10- epi-γ-eudesmol (7.8%) and curcumenol (5.3%). The fruit oil was mainly composed of furanogermenone (54.8%), trans-β-ocimene (8.8%), sabinene (6.4%) and germacrene D (4.0%). The major constituents were isolated and characterized on the basis of NMR spectroscopic data. The furano sesquiterpenoids, the major constituents of N. pallens, are of chemosystematic and commercial importance.

Kalanchoe Pinnata

The essential oil from the leaves of Kalanchoe pinnata (Lam.) Pers. (Crassulaceae), collected in the Venezuelan Andes, was obtained by hydrodistillation and its composition determined by gas chromatography (GC) and gas chromatography/mass spectrometry (GC/MS). Nineteen compounds were identified, representing 95.2% of the oil. The most abundant components were α-curcumene (44.7%), 1-octen-3-ol (18.1%), β-curcumene (4.9%), and β-caryophyllene (3.7%).

Hydrodistilled essential oil and the corresponding headspace volatiles of Bosnian wild growing Thymus praecox ssp. polytrichus (A. Kern. Ex Borbàs) Jalas and Thymus praecox ssp. skorpilii (Velen.) Jalas were subjected to capillary GC-MS analysis. This work presents a detailed essential oil analysis of these two rare Thymus subspecies from Bosnia, as well as the very first report on their headspace composition. Eighty-seven volatile constituents were identified in four samples. Two alcohols were the major constituents in the essential oil of T. praecox ssp. polytrichus, a monoterpene, linalool (13.9%), and a sesquiterpene, ( E)-nerolidol (10.4%), while linalyl acetate (36.7%) and linalool (22.7%) were the most abundant volatiles in the corresponding headspace sample. Oxygenated monoterpenes (57.5%) predominate in the essential oil of T. praecox ssp. skorpilii with linalyl acetate (28.7%) and linalool (14.4%) as the main representatives. Headspace sample of this subspecies also showed richness in linalyl acetate (52.4%), while the second most abundant compound was α-pinene (14.5%), a monoterpene hydrocarbon.
