“…The extraction of essential oil was performed by adding 250 g of the aerial plant part in 200 mL distilled water and heating for 3 h at 100 • C using a Clevenger type apparatus [26]. The TEO vapours were condensed at 8 • C and collected in glass bottles.…”

Candida spp. is the most common microbial pathogen in fungal infections. There has been a tremendous increase in cases of candidiasis, especially among critically ill non-neutropenic patients. Candida albicans’ isolates were procured from the Prince Sultan Military Hospital, Riyadh, KSA. The isolates were characterized for their identification using CHROMagar, carbohydrate metabolism, germ tube formation, and RAPD-PCR techniques. The essential oil of Thymus vulgaris was obtained by hydro-distillation and characterized to decipher the major bioactive phytoconstituents. The antifungal activity of the thyme essential oil (TEO) was evaluated against fluconazole-resistant C. albicans isolates. The major phytocomponents identified by GC/MS were thymol (68.1%) followed by γ-terpinene (8.9%), cymol (7.7%), caryophyllene (1.1%), linalool (1.4%). The TEO successfully reduced the growth of C. albicans isolates. At very low doses, the TEO proved to be fungi static and fungicidal. TEO also effectively inhibited the germ tube formation and budging of fungal pathogens. The time kill assays have shown that TEO was more effective against drug resistant clinical isolates than fluconazole. This study provides an array of experimental evidence regarding the therapeutic efficacy of TEO against the drug-resistant clinical isolates of C. albicans. The findings may be used in the development of a new antifungal agent accordingly.

“…The mass transfer rate, then, reaches a zero when the equilibrium state is occurred. In fact, the dissolution process and diffusion process are dominated in the extraction of the EO according to the different concentrations between the solid phase and bulk liquid phase [18].…”

This work aims to study extraction of essential oil (EO) from peppermint leaves using hydro-distillation methods. The peppermint oil extraction with hydro-distillation method studied the effect of the extraction temperature on the yield of peppermint oil. Besides, it also studied the kinetics during the extraction process. The second-order mechanism was adopted in the model of hydro-distillation to estimate many parameters such as the initial extraction rate, capacity of extraction, the constant rat of extraction at various temperatures and activation energy. The results showed that the extraction process is a spontaneous process, since the Gibbs free energy has a negative value at all studied temperatures. For example the Gibbs free energy at (70, 80, 90, and 100 ºC)were (-2.93, -3.84, -4.75, -5.66) respectively.

Eucalyptus oil is used in a wide range of medicinal and other uses, and the current study aims to estimate the median lethal dose LD50 of eucalyptus oil of Eucalyptus camaldulensis and estimate the pathological effect of eucalyptus oil in mice. Eucalyptus oil was obtained in the study by extracting the leaves of the plant Eucalyptus camaldulensis using hydrodistillation. Toxicity testing was performed by dividing mice into groups that you treated with different doses of eucalyptus oil 1200, 1600, 2000, and 2400 mg/kg. The current study showed that the average lethal dose, the LD50, was 1820 mg/kg. The study suggested the emergence of clinical signs in mice when consuming eucalyptus oil in high doses, such as slow movement, suffocation, and convulsion, compared with the control group and the group that administered a lower dose, It was observed that high doses of eucalyptus oil could cause damage to the lung, liver, kidneys, and heart, as the lung was the organ most affected by the oil, followed by the liver, kidneys, and then the heart, and it was less affected by eucalyptus oil, and this indicates that eucalyptus oil, when administered orally in high doses, causes clear toxicity effects. Eucalyptus oil is a safe medicine for external use. Keywords. Eucalyptus oil, LD50; Administrated; Lung; Liver; Heart; Kidney; Mice.
