Phytochemical Analysis, Antioxidant, and Anti-Microbial Activities of Suaeda vermiculata n-Hexane Extract in Comparison to the Plant's Hydrodistilled Volatile Oil

Background: Suaeda vermiculata, a halophyte found in central Saudi Arabia, used as remedy for jaundice, liver diseases, and viral infection. Study aim: Chemical identification biological evaluation the n-hexane extract of S. vermiculata. Methods: An assay antimicrobial antioxidant potentials contents volatile oil plant’s aerial parts were analyzed through GC-MS analysis. Results: A total 24 constituents representing 73.74 % identified wherein bornyl acetate, γ-elemene, phytol major ratio. The inhibited DPPH-radicals inhibitions at 27% efficiency 10 mg/ml concentration which was lower than DPPH-reactivity. activity relatively weaker oil, except against Candida albicans that showed IZD values 19 mm with MIC value 5.2 while 26 4.7 observed extract. Conclusion: Despite high extractive value, solvent is not recommended extraction oxygenated-terpenic components, considered responsible activities fully extracted. potent inhibition C. can be source further investigation bioactivities its constituents.
