Introduction Gerbera piloselloides (L.) Cass. and delavayi Franch. are increasingly recognized for their medicinal properties, particularly among ethnic minority communities in southern China, where they used heat-clearing, detoxification, cough relief, lung expulsion, asthma alleviation. Despite traditional use, these species have been subjected to limited research regarding biological activities, leaving a gap scientific understanding. Methods This study was designed investigate the essential oil (EO) compositions, as well antioxidant antimicrobial properties of G. . The EOs were extracted via hydrodistillation analyzed using gas chromatography-mass spectrometry (GC-MS). potential assessed through ABTS DPPH free radical scavenging assays, along with ferric reducing power (FRAP) method. activity evaluated against five bacterial strains, including two Gram-positive ( Staphylococcus aureus , Listeria ) three Gram-negative Salmonella Escherichia coli Pasteurella multocida species, broth microdilution technique. Results from (EOgp) yielded 0.14% found contain 24 compounds. It demonstrated high assay exhibited strongest antibacterial effect vitro In contrast, (EOgd) had higher yield 0.26% contained more complex composition 100 showed superior both FRAP assays also highest Discussion findings this confirm that possess significant natural sources antioxidants agents, warranting further exploration development into therapeutic products.
