Recherche de propriétés antibactériennes dans les graines de Salvia hispanica L. « Graines de chia »

Abstract

The Salvia hispanica plant is an annual herbaceous plant of the Lamiaceae family, which has been traditionally used for the treatment of various diseases since ancient times. Salvia hispanica is endowed with bioactive components that exhibit antioxidant, anti-inflammatory, and antimicrobial activities. For this, the objective of this study is to search for antibacterial properties in the aqueous solution of Salvia hispanica seeds, against the reference strains S. aureus, P. aeruginosa and E. coli. The results obtained show the presence of antibacterial activity in these seeds with an IC50 of 0,49; 0,60 and 0,20 mg/mL and an MIC of 0,26; 1,04 and 0,13mg / mL against, respectively, S. aureus, P. aeruginosa and E. coli strains. The pH and heat treatments affected the antibacterial activity of the Salvia hispanica seed solution. Also, the results showed that the liquid medium is better suited for researching this type of activity than the solid medium.
