- Abstract
Pulicaria odora is an aromatic plant belonging to the Asteraceae family, tribe Inuleae with approximately 100 species, well known in morocco and traditionally used as a remedy for its anti-inflammatory activity. The aim of this work is to highlight the antibacterial activity of leaves and roots of this plant. Three different solvents namely methanol, acetone and chloroform were used for the extraction of phenolic compounds. The methanolic extract of leaves recorded the highest total polyphenols content (TFC) (90 µg CE/g of DM) and flavonoids (11.34 µg QE/g of DM). Antibacterial activity of the different extracts showed that most of the bacterial strains tested were sensitive to Pulicaria odora extracts. Gram positive bacteria (B. subtilis and S. aureus) are more sensitive than Gram negative bacteria (E. coli and P. aeruginosa). Results showed that S.aureus was the most sensitive, with the largest inhibition diameter (30.5 mm) obtained with the acetonic extract of roots, whereas P. aeruginosa was the most resistant (00 mm) for the chloroformic extract of leaves. Leaf extracts were the most actives against S. aureus and P. aeruginosa, with MIC/MBC equal to 1/1.4 mg/mL.
