“…22 Dados de literatura indicam que altas temperaturas, como as utilizadas na extração dos óleos essenciais por hidrodestilação, podem levar à degradação do germacreno D ou induzir um rearranjo molecular, originando outros compostos de natureza sesquiterpenoídica, considerados artefatos. 23 O humuleno, que ocorre em maior concentração nos óleos dos caules aéreos e rizomatosos da espécie em estudo, já foi identificado no óleo essencial das folhas de S. grisebachii Baker. 24 Para este composto, bem como para o α-cadinol, constituinte majoritário do óleo essencial das folhas de S. crassiflorus var.…”

Recebido em 20/4/07; aceito em 3/12/07; publicado na web em 24/7/08 COMPOSITION AND ANTIBACTERIAL ACTIVITY OF THE ESSENTIAL OILS OF Senecio crassiflorus var. crassiflorus. The essential oils of leaves, aerial and underground stems of Senecio crassiflorus var. crassiflorus were extracted by hydrodistillation and their analyses were performed by GC/MS. Qualitative and quantitative differences have been found between the analyzed parts. The main compounds of the essentials oils of the leaves were found to be oxygenated sesquiterpenes, while the oils from the aerial and underground stems showed sesquiterpene hydrocarbons as major constituents. Furthermore, the essential oils were tested against Staphylocccus aureus, Escherichia coli, Pseudomonas aeruginosa and Bacillus cereus. The essential oil of the leaves was shown to be the most active.

“…Like most plants used for medicinal purposes, Stachys taxa have been submitted to several investigations in order to determine the content of biologically active compounds. As many other representatives of the family Lamiaceae, Stachys species also produce essential oils, but in spite of the large size of this genus, the composition of volatile compounds is known only in a small number of species (Maly, 1985;Cakir et al, 1997;Mariotti et al, 1997;Pélissier et al, 1999;Chalchat et al, 2000Chalchat et al, , 2001Skaltsa at al., 2003;Tirillini et al, 2004;Bilusic Vundac et al, 2006;Radulovic et al, 2007).…”

Stachys menthifolia Vis. (Lamiaceae) is an endemic species from the Balkan Peninsula spread throughout Albania, Greece, Montenegro, and Croatia. This article presents the first investigation of the essential oil composition of this species from Croatia. Aerial parts of the plant were collected from three different natural habitats in the region of Biokovo Mountain. The studied populations showed similarity in qualitative, but not in quantitative, composition of their essential oils. Hydrodistilled volatile oil obtained from the plant material of S. menthifolia was subjected to gas chromatographic analysis coupled to mass spectrometry. More than 100 compounds were identified in the three samples, representing 86.8-90.8% of the total oil. The terpene profile of S. menthifolia is characterized by a high content of oxygenated sesquiterpenes (48.4-58.9%) and diterpene hydrocarbons (3.5-25.2%), with 8-alpha-acetoxyelemol (6.9-21.3%), abietatriene (3.5-21.1%), and 4'-methoxyacetophenone (4.5-17.0%) as the main constituents.

“…Moreover, while conservation of a particular terpenoid skeleton is established to be useful in reflecting chemotaxonomic features within the Lamiaceae family [22], our results on essential oil profile of S. brachyodon indicate that its volatiles cannot be reliable taxonomic markers.…”

Essential-oil profile of Salvia brachyodon Vandas, an endemic Dinaric species transferred from Adriatic Coast to the continental climatic conditions, was determined. Hydrodistilled oils obtained from the plant material collected in three-year field trial were subjected to the detailed GC/MS analysis. Hundred and fifty volatile compounds were identified in four samples. Comparison of the chemical composition of the isolated essential oils showed that population collected one year after transfer preserved sesquiterpene character of its oil (74.3%), while all subsequent samples gave the oils of monoterpene type with 1,8-cineole as the principal constituent (22.2-42.3%). The high degree of variation in the qualitative and quantitative composition of the volatile constituents revealed the strong influence of environmental conditions on the nature of plant chemical composition that has an important role in a plant adaptation.
