Summary: This study aimed to investigate the effects of different drying methods on the drying kinetics, effective moisture diffusivity, color properties, total phenolic content, antiradical activity, and essential oil composition of lavender and lavandin genotypes. The results showed that drying was best described by the Wang & Singh mathematical model, and greenhouse drying was the fastest method in terms of drying duration. Open-shade drying method significantly positively affected the bioactive characteristics and essential oil composition.

Summary: This study demonstrates that the encapsulation of lavender and peppermint oils in Arabic gum/maltodextrin microparticles by spray-drying is a feasible approach for converting liquids to solids, making them more suitable for use in powder technology. The type and concentration of wall material, as well as the type of essential oil, significantly impact the encapsulation process and the characteristics of the final particles.

Summary: The study found that Lavandula angustifolia essential oil has anti-Toxoplasma activity, showing dose-dependent inhibition at safe concentrations by potentially reducing parasite invasion through detrimental effects on morphology changes. This suggests that Lavandula angustifolia essential oil could be a potential drug for treating toxoplasmosis.

Summary: Ilex rotunda, a plant used in traditional medicine, was investigated for its antioxidant activity. The twig extract showed the highest antioxidant capacity, and the n-butanol fraction exhibited the most significant antioxidant effect. Eight marker compounds were isolated and their structures were determined. Compound 7, 4,5-dicaffeoylquinic acid, demonstrated potent antioxidant activity and penetration across the blood-brain barrier, suggesting its potential as a therapeutic candidate for central nervous system diseases.

Summary: This study investigated the effects of different fermentation times on the phenolic content and radical scavenging activity of Kinema, and determined the optimal fermentation time using one-factor response surface methodology. The numerical optimization suggested an optimal fermentation time of 29.6 hours, which resulted in significantly higher total phenolics and flavonoid contents and lower DPPH radical scavenging activity compared to traditionally fermented Kinema. Moreover, the optimized Kinema had significantly higher overall sensory scores. These results indicate that fermentation time affects the amount of bioactive constituents in Kinema.

Summary: This study aimed to investigate the response of lavender plants to heavy metals stress under arbuscular mycorrhizal fungi (AMF) inoculation. The findings showed that AMF inoculation enhanced the uptake of lead and nickel by lavender plants and increased the activity of antioxidant enzymes and total antioxidant activity. The results suggest that AMF inoculation can enhance the phytoremediation ability of lavender plants.

Summary: The study compared the composition and proregenerative properties of commercially available French narrow-leaved lavender oil and locally cultivated Polish narrow-leaved lavender oil, finding that the self-manufactured oil had lower linalool content and higher lavandulyl acetate content. The lavender oils showed a concentration-dependent effect on IL-6, IL-8, and VEGF production by keratinocyte cell line, with the in-house preparation performing significantly better in increasing VEGF production in vitro cell models.

Summary: This study aimed to determine the activity of lavender (Lavandula angustifolia) essential oils from different cultivars and morphological parts in combination with fluconazole against Candida albicans ATCC 10231 strain. The combination of fluconazole with essential oils from flowers and leafy stalks of two tested lavender cultivars showed synergistic interaction. The enhancement effect of fluconazole antifungal activity was stronger with essential oils extracted from flowers and leafy stalks of the 'Blue River' cultivar. Similar synergistic interaction was found with linalool, one of the main components of lavender essential oils.

Summary: This study aimed to analyze the changes in phytochemical compositions of Lavandula stoechas L. treated with biotic (chitin) and abiotic (copper nanoparticle) elicitors. The results showed that the contents of total phenolics, flavonoids, anthocyanins, and flavonols were highest in the elicited plants. Additionally, the elicitors played a role in increasing the percentage of secondary metabolites.
