Abstract
-
This study examines how extraction conditions influence the phenolic composition and antibacterial activity of Arbutus unedo L. leaf extracts. Neutral and acidified protocols were compared using phytochemical screening and in vitro antibacterial assays against Staphylococcus aureus, Escherichia coli, and Pseudomonas aeruginosa. Antibacterial activity was assessed by microdilution with CFU confirmation, while TLC provided chemical profiling. Neutral extracts showed no activity, whereas acidified extracts inhibited S. aureus and weakly affected P. aeruginosa, with no effect on E. coli. Results highlight the importance of extraction methodology and support further investigation into phenolic compounds and synergistic antibacterial strategies.
