The efficiency of vacuum distillation (150 mmHg) over conventional distillation at atmospheric pressure was assessed on the quantitative and qualitative characteristics of these leaf oils, known for high monoterpene content and possessing lower boiling points. The oil yields were comparatively lower in vacuum distillation (0.25%) than conventional distillation (0.28%).

Further, the ratio of monoterpenoids to sesquiterpenoids in the vacuumâdistilled oil was 10 times higher (10.5) than the conventionally distilled oil (1.0). These variations are attributed to the fact that in vacuum distillation, the constituents with lower boiling points are easily distilled off, leaving behind the higher boiling point constituents, which are otherwise extracted in the conventional distillation. In antifungal assays of these essentail oils against the fungal pathogens Fusarium oxysporum f. sp. dianthi and Alternaria dianthi , infecting carnations, and F. oxysporum f. sp. gladioli and Curvularia trifolii f. sp. gladioli infecting gladioli, the residual oil showed better antifungal activity over other oil samples at each of the tested concentrations. Either the high content of sesquiterpenoids or the combined effect of the composition/ratio of monoâ and sesquiterpenoids might have enhanced the antifungal activities. These studies clearly established the significance of a waste yielding useful products and the usefulness of the modified water distillation methods for producing essential oils with highâquality profiles in terms of chemical composition and antifungal activity, except for oil yields.

Non-target toxicity experiments were carried out on four species of aquatic larvivorous organisms, including fishes, backswimmers, and waterbugs. The essential oil from E. uniflora leaves tested on An. subpictus, Ae. Albopictus, and Cx. tritaeniorhynchus showed LC<sub>50</sub> of 31.08, 33.50, and 36.35 μg/ml, respectively.

Respective essential oil was evaluated for anti-proliferative, antibacterial and antioxidant activity. METHODS: Essential oils were extracted by hydrodistillation and then analysed by gas chromatography coupled to mass spectrometry (GC-MS). Anti-proliferative activity was determined against human cell lines (MCF7 and MDA-MB231, HT29 and HCT116) by the thiazolyl blue tetrazolium bromide (MTT) procedure. Antioxidant activity was evaluated by diphenyl 2 pycril hydrazil (DPPH) assay. Antibacterial activity was determined against two Gram-positive and two Gram-negative bacteria by microdilution method. RESULTS: The essential oil from olibanum of Boswellia papyrifera contained mainly alcohol and ester derivatives (46.82%) while monoterpenes (69.84%) dominated in Corton zambesicus oil. Sesquiterpenes were the most highly represented classes of terpene derivatives in Cyperus schoenanthus (71.59%) and Cyperus rotundus (44.26%). Oil of Cymbopogon schoenanthus revealed the best anti-proliferative activity against HCT116 cell line with IC50 value at (19.1 ± 2.0) μg/mL. Oil of Croton zambesicus showed the best antioxidant activity [EC50 (4.20 ± 0.19) mg/mL]. All oils showed good antibacterial activity against Escherichia coli, Bacillus subtilis and Staphylococcus aureus with minimum inhibitory concentration (MIC) value ranged from 16 to 250 μg/mL.

Samples of leaf and inflorescence volatile oils obtained from individuals located at two different regions of Brazil were analyzed by GCâMS and the data were submitted to chemometric analysis.

The influence of soil nutrients, mainly Ca and P, was also observed in the composition of the volatile oils. Climate also seems to affect the constituents of the volatile oils, mainly the contents of leaf sesquiterpenes of individuals growing in areas with higher average temperatures and solar radiation levels.

SHSâSPME allowed all the plant material to be analyzed under the same conditions despite its wide-ranging composition. This is not always possible with other extraction methods. Using an apolar poly(dimethylsiloxane) (PDMS) phase, numerous terpenoid hydrocarbons, together with alcohols, cyclic ethers, and esters, were extracted. Its ease of use and the high resolution of the chromatographic profiles obtained make SHSâSPME well suited to the rapid characterization of the main components of the volatile fraction of plants. Of the nine plants studied, four (Meum athamanticum, Pimpinella saxifraga, Achillea millefolium, and Thymus pulegioides) exhaled more than 60 different volatile components. Certain terpenes present in large amounts in these plants might help link dairy products to grazing pasture, thus improving food traceability.

Data were evaluated with uni- and multivariate techniques. The variation in the oil composition was related to the relative proportion of the constituents and not to the presence/absence of a particular component. Weather conditions in 1997 favored linalool and camphor in both landraces. Location, fertilization, and weediness also affected the chemical profile.

Results revealed that the crops planted between September to December produced significantly higher herbage yield measured directly, or after drying compared with that of February planted crop. September planted crop yielded the highest amount of artemisinin. Therefore, the plants established during pre-winter (August-September) weather and allowed to grow through the entire winter synthesized and accumulated more artemisinin than plants established during early (October-November) and late (February) winter periods. The crop planted in November (or the beginning of winter) was found to be significantly superior to a crop planted in August, January or February, both in herbage production and oil yield. The September planted crop yielded relatively less oil than the November planted crop but the artemisia ketone content of the oil of the former was better. It is concluded that the artemisinin content is dependent on the weather conditions, and high yields of artemisinin do not necessarily depend on high dry matter production by the crop. Under northern Indian plains conditions, the Artemisia annua crop should be planted in September for getting higher artemisinin yield with superior quality of oil as measured by the artemisia ketone content, and in November for obtaining maximum oil yield.'),(235,'10.1080/10412905.1997.9699459','A Study on Anti-Inflammatory and Peripheral Analgesic Action of<i>Salvia sclarea</i>Oil and Its Main Components','Journal of Essential Oil Research',1997,'https://doi.org/10.1080/10412905.1997.9699459',67,'https://openalex.org/W2011466884','Abstract Activity against the acute inflammatory process induced by carrageenin and histamine in rats and the anti-nociceptive effect in mice were investigated after administration of Salvia sclarea oil and some of its constituents.

The anti-inflammatory action was more conspicuous in the carrageenin-induced edema, where it produced the equivalent effect of a 5 mg/kg dose of indomethacin, than in the histamine-induced edema. The effect was correlated to the presence of methyl chavicol, linalool, α-terpineol and linalyl acetate. The results show that these constituents produce less anti-inflammatory action when administered separately than the oil in toto, and are also less effective than the oxygenated fractions obtained by Flash chromatography of the oil.

The enantiomeric distribution of α-pinene, β-pinene, sabinene, limonene, linalool, citronellal and α-terpineol was studied by simple and reliable enantioselective GC methods involving either a chiral capillary column or an on-line coupling of non-chiral and chiral capillary columns.
