Fresh leaves and fruits of C. arizonica were steam distilled and the oils were analyzed qualitatively and quantitatively by GC and GC/MS. Different methods of rapid TLC screening, DPPH assay, desoxyribose assay, assay for site-specific reaction and non-enzymatic lipid peroxidation were employed to evaluate possible antioxidant activity of the oils and their main components, as well as the positive controls. The main components of these essential oils were a-pinene, cymene, myrcene, limonene, sabinene hydrate, cedrane and germacrene D. In rapid TLC screening, the tested compounds mainly showed antioxidant activity. In DPPH assay the stronger antioxidant effects were shown by the fruit oil of C. arizonia. In deoxyribose degradation assay test, most of the tested compounds showed some antioxidant effects. In non-enzymatic lipid peroxidation test, most antioxidant activity was shown by the fruit oil.

This work is aimed at adapting the green technology of using supercritical CO2 (SC-CO2) as solvent in a batch process to extract Melaleuca cajuputi leaves. The plant leaves were collected from Trengganu, Malaysia. Cajuputi extract analyses were performed by GC and GC/MS. The maximum yields obtained were 4.2% and 6.0%, respectively, by supercritical fluid (SFE) and solvent extraction (SE). Several compounds were identified and significant qualitative and quantitative differences were observed under different conditions. The major components of Cajuputi oil consisted of sesquiterpenes (d-elemene, b-elemene, b-caryophyllene, a-humulene, 9-epi-b-caryophyllene), their oxygenated derivatives (viridiflorol, platyphyllol, b-eudesmol, bulnesol, (Z,Z)-farnesol and (E,E)-farnesal) and polyphenolic ketones (isoeugenitine and three unknown compounds).

More than 80 compounds were identified as oil components. The leaf, flower and fruit oils were characterized by a predominance of sesquiterpenes, such as b-caryophyllene (3–5 g/100 g), germacrene D (4–14 g/100 g), b-bisabolene (32–49 g/100 g); the total amount of sesquiterpene hydrocarbons contained in each oil was 56–70 g/100 g, the oxygenated derivatives were in the range of 9–20 g/100 g. The monoterpene hydrocarbons in all samples (leaves, flowers, fruits) were contained in very low amounts, from 0.2 to 1.6 g/100 g, and were the least representative fraction of the oils. Oxygenated aliphatic compounds, especially esters, were also detected. The results can be useful to support, by means of a safe reliable sample preparation (MHD) and analytical (GC) technique, the research on medicinal plants belonging to Mediterranean flora.

Thirty compounds were identified, 16 of which were new for this plant material. The predominant group of components were sesquiterpene hydrocarbons, among which the major were: b-elemene, d-cadinene and a-selinene. By applying HS-SPME, it was possible to detect more compounds than by means of hydrodistillation. Sesquiterpene hydrocarbons were identified both in hydrodistilled essential oils and those analyzed using HS-SPME, while monoterpenes and low boiling non-terpenes were detectable only by means of HS-SPME method.

Sixty eight and 67 compounds were identified in the leaf and branch oils respectively corresponding to about 84.3% and 96.7% of the total amount of the oils. The leaf oil consists mainly of monoterpene hydrocarbons (27.4%), sesquiterpene hydrocarbons (33.0%) and oxygenated sesquiterpenes (16.3%). The major components of the leaf oil were b-pinene (10.4%), b-caryophyllene (8.6%), a-pinene (7.9%) and bicyclogermacrene (7.2%). The branch oil consists mainly of sesquiterpene hydrocarbons (59.3%) and oxygenated sesquiterpenes (24.9%). The major components of the branch oil were b-caryophyllene (17.3%), b-selinene (9.1%), bicyclogermacrene (8.9%), a-cadinol (5.8%) and spathulenol (4.6%).

Antibacterial activities against staphylococcus aureus of terpene alcohols with aliphatic carbon chains / Naoko Togashi in The journal of essential oil research, Vol. 22 N° 3 (Mai/Juin 2010)

Farnesol and nerolidol, which each contain two isoprene units, had the strongest antibacterial activities and damaging effects on cell membranes of all the terpene alcohols tested. Plaunotol, which is a diterpene, had antibacterial activity similar to that of sesquiterpenes. The relationship between the length of the carbon chain bonded to the hydroxyl group and activity suggests that the length of the carbon chain is an important determinant of antibacterial activity and cell membrane-damaging activity. It was concluded that the carbon chain length of C10-C12 was appropriate to show the activity.

Citronella oil compositions were determined by gas chromatography mass spectrometry (GC/MS). Anti-P. acnes activity of citronella oil and its major components were also investigated. After exposure with P. acnes at various concentrations of citronella oil (0–100 mL/mL), time-kill profiles, pentose leakage and electron microscopic characteristics were determined. The GC/MS results revealed that the major constituents of the oil were citronellal, geraniol and citronellol. At all concentrations above Minimum Bactericidal Concentrations (MBCs; 0.625mL/mL), this essential oil killed P. acnes in a dose-dependent manner. The intracellular materials leakage and electron microscopic characteristics evidenced that the major target sites of antibacterial activity appeared to be cell wall, cytoplasmic membrane and intracellular materials. Citronella oil exerted satisfactory bacteriostatic and bactericidal actions against P. acnes.

The three oils were chosen and tested on grated carrots inoculated with bacteria and stored at 8°C until 8 days to simulate the market sale. The most resistant of the three strains against all the tested oils was Escherichia coli, while Listeria strain was the most easily influenced. An important interaction was revealed with the packaging type: oxygen diffusion greatly influenced the bacteria survival at the end of the experiment.
