Summary: In this study, the metabolite profiles of essential oils (EOs) from plants in the Atlantic Rainforest were determined, and their antimicrobial and biocidal activity were evaluated. The results demonstrated the antimicrobial potential of EOs and revealed novel macromolecular targets, as well as highlighted the chemical diversity of native species.

Summary: The chemical composition of essential oils from leaves and bark of white (WM) and black (BM) morphotypes of Salmea scandens was analyzed. The results showed that the main components of bark oils were aliphatic hydrocarbons and oxygenated sesquiterpenes, while oxygenated sesquiterpenes and oxygenated aliphatics stood out in leaf oils. Nine components with antimicrobial and anti-inflammatory potential were identified. The hierarchical clustering and principal component analysis confirmed the variability of the essential oils. These results suggest that WM may have a better therapeutic effect in traditional medicine for treating infectious and inflammatory processes.

Summary: The increase in world population has resulted in higher demands for agricultural products. However, the use of chemical pesticides has caused concerns over their impact on human health and the environment. As a result, researchers have turned to biological controls using beneficial microorganisms, but the development of biofungicides has faced challenges. This review focuses on the gap between the screening of biological control agents and the availability of marketed products, and highlights the obstacles in terms of efficacy and legislation procedures.

Summary: The European cherry fruit fly is a significant pest of sweet and sour cherry fruit, which is challenging to control with conventional insecticides. Research has identified three volatile compounds that are attractive to females of this species, suggesting the potential for new attractants. Understanding the reactions of flies to host-plant volatile organic compounds could aid in the development of effective pest management strategies.

Summary: Exotic water primroses (Ludwigia spp.) are aggressive invaders in aquatic ecosystems worldwide, with limited management options. Despite the potential of biological control, little is known about their natural enemies. Studying the biology and host range of the flea beetle Lysathia flavipes showed it lacks sufficient host-specificity for consideration as a biocontrol agent of exotic Ludwigia spp. in the USA.

Summary: This study explored the aroma and nutrient profiles of six cruciferous vegetables and found extensive variation among them. The differences provided a basis for distinguishing these vegetables, and several new markers were discovered. Additionally, this study compared the edible and inedible parts of cruciferous vegetables for the first time, suggesting new potential uses as functional foods.

Summary: This study investigated the volatile flavor products of nonenzymatic thermal degradation of glucosinolates. The results showed that increasing temperature and time accelerated the degradation rate, and different matrices and solution pH values had varying effects on the degradation.

Summary: This study compared the analysis of carbohydrates using four common chromatographic methods coupled to mass spectrometry. It was found that gas chromatography and reversed-phase liquid chromatography, after derivatisation, showed superior separation performance compared to the other methods. Targeted analysis using different working modes of the mass spectrometer improved sensitivity and repeatability, with RP-LC-MS in MRM mode after derivatisation being the most suitable method for monosaccharide analysis.

Summary: The genetic diversity among grapevine cultivars is low, and breeding for agronomic traits increases the contents of soluble sugars, total phenolics, and anthocyanins in grape juices. The metabolic profiles of the juices accurately reflect the genetic distances between cultivars.

Summary: The optimized SPME-GC-MS method was used to quantify and qualify volatile metabolites in alfalfa glandular trichomes, leading to the detection of tissue-specific volatile metabolites. HCA and PCA analysis demonstrated that the method effectively differentiated metabolic profiles of different tissues.

Summary: Biological control is effective for fungal and bacterial plant disease management, but the inconsistent performance of bacterial biocontrol agents and pathosystem factors and environmental conditions can limit their commercial use.

Summary: Curculio elephas, an important pest of European chestnut in Europe, was studied to identify potential volatile organic compounds (VOCs) from chestnut reproductive tissues that attract adult individuals. VOCs were collected and analyzed using the dynamic-headspace technique combined with GC-MS. The results showed that chestnut trees release different VOCs depending on their developmental stage, and the antennae of both male and female chestnut weevils respond to certain compounds. This research contributes to the development of efficient monitoring tools for the detection and management of this pest.
