is a cosmopolitan saprophytic fungus that infests several foodstuffs and is associated with adverse effects in humans. In Senegal, significant losses of groundnut production are mainly due to contamination caused by this species. This study evaluated in vitro antifungal activities of , and essential oils against isolated from peanut seeds. Essential oils obtained by hydrodistillation of rhizomes of the two species and leaves of were analyzed with GC-DIF and GC-MS. The essential oil yields from , and were 1.1%, 1.3% and 1.7%, respectively. These three samples had the following chemotypes: (i) mustakone (21.4%)/eudesma-4(15)-7-dien-1β-ol (8.8%)/caryophyllene oxide (5.9%), (ii) caryophyllene oxide (25.2%)/humulene epoxyde 2 (35.0%) and (iii) geranial (46.6%)/neral (34.6%). The three oils tested inhibited the growth of at concentrations between 100 and 1000 ppm. The oil was the most effective with total clearance of on PDA. For the essential oils of (93.65%) and (78.11%), the highest inhibition rates were obtained with a 1000 ppm dose. Thus, oil could be used safely as an effective protector of groundnuts against .

Bacterial resistance, a global public health concern prioritized by the World Health Organization, is particularly alarming in Staphylococcus aureus and Escherichia coli. Urgently addressing this, the search for new antibiotics has turned to plant essential oils. Our study focused essential oils derived from Colombian plants Croton killipianus, Croton smithianus, Croton leptostachyus, Croton hondensis, and Croton gossypiifolius.

Monoterpenes (MTs), the major constituents of plant essential oils, cover a broad spectrum of biological activities through their interaction with biomembranes. MTs are highly hydrophobic substances with a net electrical dipole, but are not clearly amphipathic. As a result, they aggregate at increasing concentrations in aqueous media, and in membrane environments their behavior changes from dynamics modulators to disruptors.

Volatile compounds have a deep influence on the quality and application of the medicinal herb ; however, little is known about the effect of UV-B radiation on volatile metabolites. We herein investigated the effects of UV-B exposure on the volatile compounds and transcriptome of to assess the potential for improving its quality and medicinal characteristics. Out of 733 volatiles obtained, a total of 133 differentially expressed metabolites (DEMs) were identified by metabolome analysis.

: Essential oils (EOs) have been exploited by humans for centuries, but many sources remain poorly investigated, mainly due to the low yields associated with conventional extraction. Recently, new techniques have been developed, like solvent-free microwave extraction (SFME), able to enhance efficiency and sustainability. The use of L.
