The essential oils obtained by hydrodistillation of the aerial parts of Valeriana parviflora (Trevir) BM Vadillo, an endemic species of the Venezuelan Andes, collected from the same location in two different seasons (dry and rainy) of the year, were analyzed by GC/MS. The essential oil obtained during the dry season showed linalool (11.9%), eugenol (8.9%), p-menth-1-en-9-al (8.7%) and α-terpineol (7.7%) as main components, while the oil obtained from the rainy season collection showed o-xylol (16.2%), 3-methyl isovaleric acid (10.6%) and geranial (9.5%) as major compounds. Some of the differences in the composition of these oils might be due to the climatic conditions at the time of harvesting.

There is a growing search in the chemical composition of essential oils, as they have biological and pharmacological activities. Among the plants with homogeneous composition in essential oils stands out the species Eremanthus arboreus (Gardner) MacLeish, (Asteraceae) popularly known as the “candeeiro”. This plant species is native to Chapada of Araripe - Ceará, Brazil. The objective was to characterize chemically the constituents of the essential oil (OE) of E. arboreus by means of Gas Chromatography and perform a review of its biological and pharmacological activities. The botanical material was collected in Chapada of Araripe, Barbalha - CE, Brazil, in April 2014, the extraction and collection of OE was done in Clevenger apparatus. The chemical composition of the OE was performed by Gas Chromatography coupled to Mass Spectrometry (CG/MS). As for the review, specialized scientific bases (Scopus, Scielo and Web of Science) were consulted. According to the results, 8 constituents were identified, where α-Bisabolol is mentioned as being the main component of the essential oil of this species. As for the biological and pharmacological activities of the OE, it was demonstrated that the species has the following activities: antimicrobial, larvicide, anti-inflammatory and antinociceptive. Eremanthus arboreus is a species with great pharmaceutical potential and also an alternative for industries that target products based on the constituent α-Bisabolol.

The essential oil ofBetula pendulaRoth. buds was obtained using both hydrodistillation and microdistillation techniques and their chemical compositions were analyzed using both gas chromatography (GC) and gas chromatography–mass spectrometry (GC-MS). Overall, more than 50 compounds were identified representing 80% and 92% for hydrodistillation and microdistillation, respectively. The main components (by hydrodistillation and microdistillation, respectively) found were α-copaene (12% and 10%), germacrene D (11% and 18%) and δ-cadinene (11% and 15%) in the analyzed essential oils. The microdistillation technique proved to be a useful tool and compliant alternative when compared to hydrodistillation.

The aim of the present study was to investigate and identify the essential oil constituents of Leucas indica (L.) R.Br. (Lamiaceae). The chemical composition of the hydro-distilled essential oil was obtained from the flowering aerial parts of L. indica for the first time. The oil was analyzed by gas chromatography equipped with flame ionization detector (GC-FID) and gas chromatography coupled with mass spectrometry (GC/MS). Fifty-six compounds were identified, representing 99.1% of the total oil. The main constituents were β-caryophyllene (51.1%) and α-caryophyllene (10.2%). The oil was found to be rich in sesquiterpene hydrocarbons (71.8%).
