The use of β-caryophyllene secondary organic aerosol particles as seeds for smog chamber simulations has been investigated. A series of experiments were carried out in the Manchester photochemical chamber as part of the Aerosol Coupling in the Earth System (ACES) project to study the effect of seed particles on the formation of secondary organic aerosol (SOA) from limonene photooxidation. Rathe...

Whitefly (Bemisia tabaci) is an important insect pest, causing severe damage to agricultural crops. The pest was recorded in a commercial rosemary (Rosmarinus officinalis, Lamiaceae) field, colonizing rosemary variety (var.) '2', but not '11'. A series of field and controlled laboratory choice bioassays confirmed the observed phenomenon. Mature potted plants of the two varieties were randomly o...

Helicobacter pylori (H. pylori) establishes long-term infections associated with severe gastric diseases such as peptic ulceration and cancer. Exposure to an antibacterial agent can help regulate the expression levels of its pathogenic genes. In this study, we analyzed transcriptional changes in H. genes induced by β-caryophyllene. We used next-generation sequencing (NGS) analyze RNA changes, r...

The intention of this study was to compare the different parts Tunisian Ferula communis via their fatty acids, essential oils and phenolic compounds. Results showed that lipid fraction fruits leaves characterized by predominance oleic acid. Erucic linoleic acids were most abundant in stems while palmitic flowers. F. defined four chemotypes, namely isoshyobunone/6-tert-butyl-4-methylcoumarin ste...
