Antioxidant and Antimicrobial Potential of Romanian Propolis Extract Combinations: Linking Chemical Composition with Biological Activity

Background/Objectives: Propolis is a chemically complex product whose antimicrobial activity varies with geographical origin and composition. This study evaluated the chemical, antioxidant, and antimicrobial properties of five Romanian propolis ethanolic extracts (PEEs) and their combinations, focusing on antimicrobial interactions and chemical-biological relationships.
