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.
