Don subsp. microphyllum (Willd.) Nym. were analyzed by gC and gC/MS. Three different populations growing at different elevations and under different weather conditions were studied from their vegetative period to post-blooming time. Forty-eight constituents accounting for between 96.5% and 83.0% of total oils have been identified and quantified. Among the identified constituents those present in the highest percentage were neryl acetate (17.6–35.6%), nerol (3.7–14.4%) and eudesmen-5-en-11-ol (6.4–23.5%). Among them, the neryl acetal percentage decreased when 5-eudesmen-11-ol percentage increased, and limonene reached 7% relative composition. The main fraction of the oil consisted of oxygenated compounds present in higher concentrations in June.

Ducane kunzea oil contained monoterpenes (70%) including α-pinene (48.3%), 1,8-cineole (14.5%) and α-terpineol (1.9%). Oils from individual K. ambigua plants varied significantly in their content of α-pinene (0.6–62.5%), 1,8-cineole (0–11.2%), bicyclogermacrene (0.4–14%), spathulenol (0.5–12.2%), globulol (0.5–22.6%) and viridilflorol (0.3–38%). The oils from fve other Kunzea spp. had significant compositional differences from each K. ambigua oil. Kunzea sp. “Badja Carpet” had a high β-pinene content (56.1%), K. muelleri contained significant levels of allo-aromadendrene (8.0%), spathulenol (7.0%) and, among all the analyzed oils, it had the highest level of bicyclogermacrene (15.7%). Kunzea affinis contained significant levels of p-cymene (26.2%) and γ-terpinene (12.2%). Kunzea parvifolia gave an oil rich in γ-terpinene (36.5%) and p-cymene (5.0%).

Stenbergia flowers red—Polydimethylsiloxane (PDMS), blue—Polydimethylsiloxane/Divinylbenzene (PDMS/DVB) and black—Carboxen/Polydimethylsiloxane (CAR/PDMS) flbers were used. (E)-β-ocimene (50–81%) and nerol (2–19%) were found as main components. Volatiles of Muscari muscarimi were trapped by blue SPME flber over a period of three days. Main components were identified as (E)-β-ocimene (t-36%), methyl salicylate (1–21%), E-methyl isoeugenol (4–22%) and benzyl benzoate (7–56%). Volatiles of crushed bulbs of Nectaroscordum siculum were trapped on an HS-SPME (Red flber).

To explicitly study the Influence of temperature on essential oil compositions, experiments on a hybrid of Origanum vulgare x Origanum majorana (containing both major monoterpene pathways of the genus Origanum, ‘sabinyl’ and ‘cymyl’-pathway) and on Origanum syriacum ssp. syriacum (only ‘cymyl’-pathway) were conducted in growth chambers. Clonally propagated plants were grown at three different temperature levels and the solvent extracts analyzed by GC/MS for their composition of essential oil compounds. The major ‘sabinyl’ compound cis-sabinene hydrate was not influenced by temperature, while temperature significantly influenced thymol and carvacrol and other essential oil compounds. Although thymol and carvacrol are closely related monoterpene phenols, they reacted to varying levels of temperature in an opposite way.

The whole fruits, representing two different ripening stages, were stored and analyzed one day after collection. More than 40 volatile compounds were identified. The relative percentage of acetates, with exception of (Z)-3-hexenyl acetate, increased in a parallel way with ripeness. Of the esters of higher organic acids, ethyl hexanoate and ethyl octanoate were present in the greatest quantity. Ethyl octanoate, which was present in the highest quantity, showed the highest increase with ripeness (from 6–8% to 15–18%), while ethyl hexanoate increased 3% to >4%. In contrast, the relative percentages of two sesquiterpenes, α-bergamotene and α-farnesene, clearly decreased with ripeness.

Ninety-two volatile components were identified in the oils, representing 81.41–94.36% of the total oils. The major compounds were cis-β-guaiene (23.25–41.23%) and δ-selinene (8.48–25.20%) in LV, δ-selinene (18.29%) and limonene (15.23%) in FL, limonene (14.01–38.72%) and β-pinene (9.88–16.31%) in FR. The oils from LV and FL were dominated by sesquiterpene hydrocarbons, whilst the FR oils were rich in monoterpenes. Seasonal changes in relative percentages of representative groups and compounds of the oils were discussed.

The major compound in the studied juniper berries was α-pinene (26.8–42.7%). There were no significant differences in the α-pinene content between the two analyzed morphotypes. The second quantitative component in the analyzed oils of unripe and ripe berries was myrcene, whose amounts differed in the studied morphotypes. Consequently, myrcene may be used as one of the indicators discriminating two different juniper chemotypes. The results obtained clearly indicate that the plants belong to two different chemotypes, producing very stable proportions of (1R)-(+) and (1S)-(–)-α-pinene enatiomers at all harvesting periods. The ratio of (1R)-(+) and (1S)-(–) enantiomers was 6.4–8.0 in the oils from morphotype with light-green berries and 2.0–2.2 in the oils from morphotype with bluish-green berries.

The oils of E. littoralis were characterized by high levels of phenylpropanoids, principally (E)-methyl isoeugenol at 37.7% in the leaf oil and 58.1% in the oils from the rhizomes and roots, the complete absence of non-terpenic aliphatic alcohols and aldehydes, and the occurrence of 8(14), 15-sandaracopimaradien-3β-ol and 7, 15-isopimaradien-3β-ol.

The results revealed 17 constituents among which octadeca-9,12,15-trienol (31.1%), hexadenoic acid (30.0%), methyl linoleate (5.7%) and dodecanoic acid (4.6%) bore the largest percentages. The antimicrobial activity of M. obtusifolia oil was studied using the agar diffusion test on 13 strains of bacteria, and against fungus and yeast. The oil showed significant antimicrobial activity against Sthaphylococcus aureus (ATCC 6538), Escherichia coli (ATCC 18739), Listeria monocytogenes (ATCC 9610), Candida albicans (ATCC 13803), Candida tropicalis (LM 37), Candida guilliermondii (LM V70) and Aspergillus flavus (LM 247).
