Abstract
Schizonepeta annua (Pall.) Schischk. has long been traditionally employed in China for its anti-inflammatory, antimicrobial, and soothing properties. This study evaluates the antibacterial properties of essential oil extracted from Schizonepeta annua (SEO) and oregano (OEO) against methicillin-resistant Staphylococcus aureus (MRSA). SEO and OEO demonstrated substantial antibacterial efficacy, with SEO exhibiting significantly enhanced antibacterial activity due to its complex composition. Mechanistic investigations revealed that both essential oils disrupt bacterial membrane integrity and biosynthetic pathways, leading to the extrusion of intracellular contents. Metabolomic analyses using GC-Q-TOF-MS highlighted SEO's selective targeting of bacterial membranes, while non-targeted metabolomics indicated significant effects on MRSA's amino acid metabolism and aminoacyl-tRNA biosynthesis. These findings suggest that SEO causes considerable damage to MRSA cell membranes and affects amino acid metabolism, supporting its traditional use and highlighting its potential in treating infections. Our results offer robust theoretical support for SEO's role as an antimicrobial agent and establish a solid foundation for its practical application in combating multidrug-resistant infections.
