antimicrobial activity, antibioresistance reversal properties, and toxicity screen of ethanolic extracts of Sommier and Levier (giant hogweed), L. (brown knapweed), and L. (Pigweed): Three invasive plants.

Background: Plants, including invasive ones, can play a significant role in the fight against antibiotic resistance and the search for new antimicrobials.

Aims: The present study aimed at assessing the antimicrobial activity, antibioresistance reversal properties, and toxicity of four samples from invasive plants, namely, (leaves and flowers), (leaves), and (flowers).

Methods: The extraction of active compounds was done with ethanol (80%, ) and the extraction yields were calculated.
