The composition of an essential oil of thyme from Germany was analyzed by GC/FID and GC-MS. Thirty constituents were identified with thymol (49.6%), p-cymene (16.4%), γ-terpinene (8.0%), linalool (4.6%) and carvacrol (4.0%) as the main compounds. In addition, olfactory evaluations were made of the thyme sample, as well as correlations of odor-impressions of the single constituents with published data. A pleasant aroma, characteristic of thyme oils was determined, with some main and minor constituents as odor-active compounds. The thyme oil possessed antiradical activity with respect to DPPH, which was greater than the activities of its major individual phenolic components, carvacrol and thymol. The oil also demonstrated a scavenging effect with respect to hydroxyl radicals (OH•), exceeding the effect exercised on the DPPH radical, the respective concentrations resulting in a 50% inhibition (IC50) being 41.4 μg/mL for DPPH and 2.9 μg/mL for OH•. Scavenging of the superoxide radical at a concentration of 50 μg/mL was 76.9%. Thyme essential oil revealed antioxidant activity in a model system comprised of a linoleic acid emulsion where, at a concentration of 0.05%, it caused 59.5% inhibition of conjugated dienes formation and 72.4% inhibition of the generation of secondary oxidized products from linoleic acid.

Geum Urbanum

Geum urbanum L. (St. Benedict’s herb, Wood Avens) belonging to Rosaceae family, is a perennial herb occuring in the moderate zone of both Hemispheres. The roots and rhizomes containing: tannins, especially ellagitannins (mainly gemin), essential oil (mainly gein), flavonoids, proanthocyanidins, triterpenes, carbohydrates. In folk medicine it was used in gastro-enteritis and liver disorders, and to induce cardiogenesis also externally for reducing the gingivitis. The results of experiments on: antimicrobial, anti-inflammatory, cardiogenic and antioxidant effects were presented.

The chemical composition of a sample of lemon eucalyptus essential oil ( Corymbia citriodora) from China was determined by GC/FID and GC/MS. Citronellal (76.3%), citronellol (5.7%) and neo-isopulegol (5.5%) were the major components. The odor of the sample was evaluated as fresh, citrus-like and mildly fruity, with a pleasant woody background note. Lemon eucalyptus oil was found to exhibit antiradical activity with respect to DPPH and hydroxyl (OH•) radicals. The effect exercised on OH• radicals significantly exceeded that observed for the DPPH radical – the respective concentrations for 50% inhibition of the radicals were 0.38 μg/mL for OH• and 344.0 μg/mL for DPPH. Furthermore, the essential oil revealed antioxidant activities in a model system comprised of a linoleic acid emulsion. At a concentration of 0.1%, inhibition of conjugated dienes-formation by 59.8% was observed and the formation of secondary oxidized products of linoleic acid by 84.7%.
