Chemical Profile, Antibacterial Activity and Antibiotic-Modulating Effect of the Hexanic L. Silk Extract (Poaceae).

The present study aimed to determine the chemical profile and to evaluate the antibacterial activity and antibiotic-modulating action of the hexanic silk extract in association with aminoglycosides. Standard ATCC 25922, ATCC 25923 and ATCC 27853 strains, as well as multi-resistant 27, 35, and 31 strains, were used in this study. Phytochemical prospection revealed the presence of the following secondary metabolites: tannins, flavones, flavonoids, and xanthones, with the main chemical constituents being identified in plant extracts obtained with apolar organic solvents such as hexane.
