In this study, the chemical composition of Magnolia essential oil (MEO) was analyzed using gas chromatography-mass spectrometry (GC-MS). The results indicated that terpenoids were primary constituents, with main components being 1,8-cineole (44.87%), (+)-citronellal (6.93%), and linalool (29.1%). antibacterial activity MEO against four target bacteria confirmed through inhibition zone assays, minimum inhibitory concentration (MIC), bactericidal (MBC) tests. bacterial growth curve demonstrated significantly inhibited effectively delayed logarithmic phase. Mechanistic studies suggested primarily acts in initial stages by disrupting cell membrane, leading to substantial leakage intracellular materials, impairing metabolic activities, inducing lipid peroxidation, enhancing oxidative stress, thereby inhibiting normal proliferation. Furthermore, MEO's antioxidant properties evaluated its scavenging effects on DPPH hydroxyl radicals, as well ferric reducing power (FRAP). findings revealed exhibited strongest followed radical scavenging, FRAP comparatively weaker. These suggest not only possesses potent but also exhibits notable activity, indicating potential for broader applications.

Essential oils (EOs) are a diverse source of bioactive compounds with remarkable therapeutic potential. Despite their significance, Conocarpus EOs have been largely underexplored. This study provides novel comparison the metabolic profiles and biological activities from C. lancifolius, erectus green, silver leaves cultivated in United Arab Emirates (UAE), offering unique insights into distinct properties potential applications. were extracted via hydro-distillation, analyzed using gas chromatography–mass spectrometry (GC-MS), subjected to chemometric analysis. Their antioxidant (2,2-diphenyl-1-picrylhydrazyl (DPPH) ferric reducing ability plasma (FRAP) assays), antidiabetic (α-amylase α-glucosidase inhibition), acetylcholinesterase (AChE) inhibition antimicrobial assessed. A total 92 metabolites identified, heptacosane nonacosane as key species discriminants. lancifolius EO showed strongest α-amylase (IC50 8.75 ± 0.54 µg/mL) 22.31 0.92 inhibitory activities, while demonstrated superior capacity 349.78 8.26 µg/mL, DPPH assay). exhibited best activity, particularly against Staphylococcus aureus (MIC 625 µg/mL). inhibited E. coli albicans In contrast, no activity Aspergillus niger. These findings highlight antioxidants for managing diabetes that may be utilized either nutraceuticals, dietary supplements or even pharmaceutical formulations. Moreover, owing significant added medical disinfectants several products. However, further, vivo validation exploration is still needed.
