Data from: Analysis of phytochemicals, antioxidants, and antimicrobial properties in non-polar extracts of Magnolia virginiana L. flowers from Saudi Arabia

Magnolia virginiana (M. virginiana) L., a native North American plant
commonly used in landscaping, is also cultivated in Saudi Arabia. This
study’s main objective and novel aspect is to examine the effects of
environmental conditions on the chemical composition and pharmacological
properties of M. virginiana plants grown in central Saudi Arabia. The
chemical diversity and biological activity of n-hexane and diethyl ether
extracts of M. virginiana flowers were analyzed. GC-MS identified aromatic
and aliphatic esters, triterpenes, steroids, and phenolic acids. The total
phenolic contents were 29.66 and 29.44 mg GAE/g for the n-hexane and
diethyl ether extracts, respectively. The diethyl ether extract showed
more potent antioxidant activity, whereas the n-hexane extract had higher
metal chelating and free radical scavenging activities. Diethyl ether
extract demonstrated more substantial antimicrobial potential, notably
against Staphylococcus saprophyticus (zone of inhibition: 20.0 ± 0.3 mm;
MIC, MBC, MBIC, MBEC: 0.78, 1.56, 1.56, and 3.125 mg/mL, respectively).
Further analysis is required to stabilize M. virginiana L. extracts for
therapeutic use.
