Abstract
ABSTRACT The biological activities of Inula graveolens in Chebba (Tunisia) salt marsh were screened. Total polyphenol (TPP), flavonoid (TF), and proanthocyanidin (TPC) contents were determined and the correlation between the phytochemistry and the antioxidant, antimicrobial, and anti-enzymatic activities was assessed. The polyphenols in the solvent extracts suggested that salinity stress may enhance the production of bioactive compounds. Antiradical activities and a potent acetylcholinesterase inhibitory power were observed. I. graveolens extracts were antimicrobial against Salmonella typhimurium, Micrococcus luteus, and Staphylococcus aureus. Total flavonoids correlated with the activity against M. luteus, while the total polyphenols content was not correlated with the antimicrobial activity.
