“…The extraction followed the methodology designated as enfleurage, replacing the fat, generally used as a solvent in this process, by NADES. 62 Other extraction techniques, like ultrasound and sealed systems, were also applied. The data obtained reveal that the yield of extraction of natural compounds from cork (Quercus suber) increases considerably when the process is carried out using NADES as a solvent instead of water or dioxane (Figure 8a, b).…”

Quercus suber cork generates bioactive components, such as phenolic acids, terpenoids, and tannins, with excellent biological properties, including antioxidant, anti-inflammatory, and antiaging activities. Aiming to design environmentally benign processes to eliminate, or reduce, the use of toxic chemicals, we propose the green extraction of bioactives from cork using natural deep eutectic solvents (NADES). Several deep eutectic mixtures were developed, through the mixture of natural compounds, namely, lactic acid, glycerol, ethylene glycol, sodium citrate, and sodium lactate, chosen according to their origin, toxicity, biocompatibility, polarity, and pH. The results revealed higher extraction yields when using NADES instead of harsh solvents like dioxane, with the extraction process governed by several physical–chemical parameters, including pH, polarity, viscosity, and density, and also by the method of extraction. Acidic NADES composed of lactic acid and glycerol, or sodium citrate, extracted a greater amount of aromatic compounds, terpenoids, and fatty acids and their derivatives. More basic eutectic mixtures, composed of sodium lactate and a polyol (ethylene glycol or glycerol), extracted predominantly low molecular weight polar compounds. The extracts range encompassed by the developed NADES, together with the associated nontoxicity, low price, and ease of preparation, establish these solvents as a green approach to extract high added-value compounds from cork.

“…The greatest difficulty of studies on the antifungal activity of essential oils depends on the sufficient production of the raw materials. In this context, different processes have been used for extraction, such as classical methods including hydro-distillation [7], effleurage [21], organic solvent extraction [8] and maceration [11]. Laboratory-scale techniques like Clevenger distillation and innovative methods such as microwave and supercritical fluid also are being studied [22].…”

Aflatoxins are secondary metabolites produced by fungi of the genusAspergillus, which occur naturally in cereals like corn, beans and rice. Aflatoxin B1causes an extensive number of toxic effects in animals and humans. This mycotoxin is a stable term and can act in low concentrations due to their higher toxicity. Management to prevent commodities aflatoxin contamination is essential during the production, mainly in pre- and post-harvest steps. A number of essential oils and aqueous plant extracts have been reported to be fungal growth inhibitors and may provide an attractive alternative to prevent aflatoxin contamination in foods. Thus, the aim of this review is to highlight recent data on thein vitroantifungal activity of essential oils and aqueous extracts from plants and discuss the perspectives of their use in food products.

“…[10] In addition, the GC/MS method was proposed to determine the components content of Calendula oil obtained by different methods. [11] GC/MS method was done for C. officinalis flowers methanolic extract analysis [12] with split injection (split ratio 1:50) and hydroalcoholic extract [13] by splitless mode.…”

Context: Alcoholic tinctures of Calendula officinalis and Eucalyptus globulus are often found in the extemporal dosage forms composition, including ointments. Their pharmacological effect is caused by the presence of biologically active substances, which determine the direction of dosage form action. Therefore, during the stability studies, it is necessary to evaluate their concentration in the dosage form. Aim: Development of the gas chromatography-mass spectrometry (GC/MS) method for the determination of the ointment with C. officinalis and E. globulus tinctures stability. Materials and Methods: In this research, the GC/MS method was used for determining the volatile compounds of both tinctures, with their subsequent determination in the compounding ointment containing them. Results and Discussions: α-cadinol, δ-cadinene, t-muurolol, γ-cadinene, viridiflorene, and α-muurolene were identified as the C. officinalis tincture main components. 1,8-cineole, α-pinene, aromadendrene, ρ-cymene, β-eudesmol, (-)-globulol, α-eudesmol, and β-pinene were isolated in the E. globulus tincture. Analysis of the ointment dissolved in chloroform had shown the presence of a small amount of the both tinctures main components. The same technique has been used to analyze the stability of ointment. The results of ointment research after storage at a temperature of 5 ± 3°C for 18 days have been indicated decreasing of the main substances of plant tinctures concentration. Conclusions: Thus, developed GC/MS method allows to determine the concentration of active components of both tinctures and can be used to study the ointment chemical stability.
