Abstract:

The essential oil of Eucalyptus cinerea is reported to possess a higher 1,8-cineole content than other Eucalyptus species. Variations in the quantitative and qualitative characteristics of E. cinerea oil produced by hydrodistillation (HD) and supercritical carbon dioxide extraction (SCE) techniques and a comparison between glycoside-bound and free volatile constituents produced by HD have been studied. It was found that HD produced higher oil (free volatiles) content (3.1%) as compared with SCE (1.1%), whereas bound volatiles constituted only about 0.4%. Gas chromatographic (GC) analysis of th

Abstract The aim of the paper was to study how the process of aromatisation with marjoram affected the composition of volatile fraction and antioxidant properties of rapeseed oil. Different methods of aromatisation were used: direct addition of marjoram essential oil, classical macerations of marjoram herb, and maceration assisted with ultrasound or microwave. The dominant aromatic component in the volatile fraction was γ-terpinene with concentration in the range from 3.15 μg/mL (microwave assisted maceration) to 8.82 μg/mL (classic maceration with shaking).

These two compounds constituted the major components of the oil and were present in equal proportions of 30% in the volatile oil extracted from the leaves and shoot tips of the Origanum plant during the preflowering stage. The percentage of carvacrol in the essential oil increased to 62% after flowering and maturation, while the concentration of thymol decreased to 14%.

The aim of this study was to evaluate the antibacterial activity of essential oil from Chamaecyparis obtusa against general infectious microbes and drug resistant strains of clinical origin. The results indicate that both essential oil and non-volatile residue have broad inhibitory activity against test strains. Essential oil and non-volatile residues showed antimicrobial activity not only against general infectious bacteria, but also against methicillin-resistant Staphylococcus aureus (MRSA) and vancomycin-resistant enterococci (VRE) strains.

The leaf essential oil of Parquetina nigrescens collected from Badary, Nigeria, was obtained by hydrodistillation and analyzed by gas chromatography – mass spectrometry. The essential oil had a simple composition with only five identified components. The oil was dominated by citral (35.0% neral and 53.7% geranial). The high concentration of citral in the essential oil likely contributes to the ethnomedicinal utility and bioactivities associated with this medicinal plant.
