The composition of essential oil isolated from the areal parts of Aster albanicus Deg, an endemic species of the central Balkans, was analyzed. In total, 111 compounds were identified, representing 98% of the essential oil. The essential oil was dominated by sesquiterpene (69.3%) and monoterpene hydrocarbons (15.9%), with germacrene D as the most abundant compound (34.7%). Several multivariant statistical methods (HCA, NJ, PCoA) were deployed to infer the relation between A. albanicus and other species belonging to this genus. Taxonomical implications are discussed.

Main Components

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.

The essential oil of the Balkan endemic species, Angelica pancicii, obtained by hydrodistillation, was analyzed by GC and GC-MS, applying the liquid injection mode. These results were compared with the chemical composition of volatiles achieved by the “headspace” injection mode, followed by GC and GC-MS (HS-GC-MS). A total of 40 compounds were identified in the essential oil (98.8% of the total oil) and 44 by HS-GC-MS (99.8% of the total oil). The most abundant class of compounds in both cases was monoterpenoids, which formed 92.7% of the essential oil (97.7% by HS-GC-MS) of total identified compounds. The major components in both cases were β-phellandrene (54.9% and 60.1%, respectively), α-pinene (14.5% and 20.1%, respectively) and α-phellandrene (4.5% and 4.3%, respectively).

Main Components

Essential oils of leaves of the endemic species Piper oradendron Trel. & Standl. (Piperaceae) were obtained from three sites of the Guatemalan Pacific slope. The yields of the essential oils obtained by hydrodistillation varied from the site of collection (0.4-1.4%). The GC/MS analysis showed that sample A (Samayac) had up to 53 peaks that were identified, B (Popoyá) showed 31 peaks and C (Bulbuxyá) showed 22; major constituents were similar in the three samples, including α- and β-pinene (28.3-46.9%), germacrene D (10.7-22.7%), and iso-spathulenol (10.2-22-3%). This is the first report on the chemical composition of the essential oil of samples of P. oradendron from different provenances of Guatemala, suggesting little variability in its main components.

The seeds essential oil of the endemic species <em>Mentha mozaffarianii</em> growing wild in the south of Iran was analyzed by gas chromatography (GC) and GC-mass spectrometry (GC-MS). Charac-terization of individual components was performed using a commer-cial mass spectrometry library, and 25 components were identified. This analysis showed the presence of 3 volatile components, including piperitenone (35.6%), piperitone (27.1%) and 1,8-cineol (10.7%) as the main components.
