The present study was aimed to find out the chemical constituents of essential oils of Artemisia nilagirica (Clarke) Pamp. and Artemisia capillaris Thunb. of Asteraceae family, growing in Garhwal region of India. The essential oils were obtained by hydro-distillation and subjected to detailed GC-MS analysis in order to determine the variation in their volatile constituents. While comparing the common constituents in both of the species, the remarkable variation was observed and it was 6.03, 3.251, 2.093, 33.73, 7.573, 15.041 and 8.00% for trans-caryophyllene, DL-limonene, α-pinene, α-thujone, β-myrcene, β-ocimene and β-thujone, respectively.

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.

Herb Species

The restinga is an Atlantic Forest ecosystem characterized by tree, shrub, and herb species that are rich sources of essential oils. In this study, we aim to quantify the essential oil content and determine the chemical constituents of fresh leaves of 14 plant species in a restinga stretch in southern Brazil. Essential oils were obtained by hydrodistillation in a Clevenger-type apparatus and analyzed by gas chromatography coupled to mass spectrometry. Campomanesia reitziana, Cortaderia selloana, and Sophora tomentosa had no essential oils. Total essential oil content ranged from 0.01% (Mikania involucrata) to 1.56% (Varronia curassavica). In total, 60 chemical constituents were identified, representing between 46.2% and 96.5% of the chemical composition of the essential oils. Limonene was the common constituent in all species in which the essential oils were present. The major constituents were ar-curcumene (15.1%) and cis-chrysanthenol (14.2%) in Ambrosia elatior; benzyl benzoate (43.5%) and benzyl salicylate (23.7%) in Aniba firmula; caryophyllene oxide (35.7%) and spathulenol (10.6%) in Austroeupatorium inulaefolium; spathulenol (19.8%) and caryophyllene oxide (14.0%) in Baccharis spicata; caryophyllene oxide (16.3%) in Eugenia astringens; curzerene (30.0%), limonene (13.0%), and germacrone (11.9%) in Eugenia uniflora; caryophyllene oxide (17.1%) and ledol (11.3%) in Lantana camara; caryophyllene oxide (27.7%) and limonene (12.7%) in M. involucrata; 1,8-cineole (19.8%) in Psidium cattleianum; limonene (10.2%) in Schinus terebinthifolius, and allo-aromadendrene (15.2%) in V. curassavica. We expect that our results can assist in selecting species of potential interest for herbal, phytotherapeutic, and cosmetic products.

The present paper reports the volatile compounds identified in the essential oils of Dasymaschalon bachmaensis N.S. Lý, T.H. Lê, T.B. Vương & N.Đ.Đỗ and Phaeanthus vietnamensis Bân (Annonanceae) grown in Vietnam. The essential oils were obtained by hydrodistillation from the leaf, stem and bark of the plants. The combined techniques of gas chromatography (GC) and gas chromatography coupled to mass spectrometry (GC-MS) were used for the analysis of the chemical constituents of the oil samples. The major constituents of the leaf oil of D. bachmaensis were limonene (25.7%), eugenol (11.5%), α-phellandrene (11.3%) and benzyl benzoate (9.0%) while the stem contained benzyl benzoate (35.3%), ( Z)-13-docosenamide (12.4%) and limonene (9.4%) In addition, ( Z)-13-docosenamide (23.2%), limonene (25.3%) and α-phellandrene (11.5%) were present in the bark. However, limonene (31.8%), ( Z)-9-octadecamide (20.2%) and α-phellandrene (13.8%) were the compounds occurring in higher amount in the leaf oil of P. vietnamensis while the bark was dominated by ( Z)-9-octadecamide (57.4%) and benzyl benzoate (15.0%). The volatile constituents of both D. bachmaensis and P. vietnamensis are reported for the first time
