Data from: Analysis of phytochemicals, antioxidants, and antimicrobial properties in non-polar extracts of Magnolia virginiana L. flowers from Saudi Arabia
<div> <p><em><span>Magnolia virginiana</span></em><span> (<em>M. virginiana</em>) L., a native North American plant, is globally cultivated for shade and ornamental purposes, including in Saudi Arabia. This study analyzed the chemical diversity and biological activity of non-polar extracts (n-hexane and diethyl ether) from <em>M. virginiana</em> flowers. The major components identified by </span><span>gas chromatography-mass spectroscopy (GC-MS) analysis were aromatic and aliphatic esters, triterpenes, steroids, and phenolic acids. The total phenolic content (TPC) of n-hexane and diethyl ether extracts was determined to be 29.66 and 29.44 mGAE/g, respectively. The extracts showed strong antioxidant activity, with the diethyl ether extract having more reducing power than the <em>n</em>-hexane extract. The diethyl ether extract also showed greater Trolox equivalent values in total antioxidant capacity (TAC) and ferric reducing antioxidant power (FRAP) assays, but the n-hexane extract exhibited higher metal chelating activity (MCA) and free radical scavenging activity (DPPH-SA) levels. The diethyl ether extract displayed stronger antimicrobial potential than the <em>n</em>-hexane extract, particularly against <em>Staphylococcus saprophyticus</em>, with a zone of inhibition diameter (ZID) of 20.0 ± 0.3 mm. The minimum inhibitory concentration (MIC), minimum biocidal concentration (MBC), minimum biofilm inhibitory concentration (MBIC), and minimum biofilm eradication concentration (MBEC) values were 0.78, 1.56, 1.56, and 3.125 mg/mL, respectively. </span></p> </div>
