“…The efficacy of O. celtidifolia extracts could be explained by its richness in various antimicrobial compounds. Previous phytochemical screenings on O. celtidifolia showed several phytochemical compounds such as flavonoids (Mazadu et al, 2018), tannins (Mazadu et al, 2018), alkaloids (Mazadu et al, 2018;Owolabi et al, 2017), terpenoids (Owolabi et al, 2017), coumarins (Togola et al, 2015), polysaccharides of pectin type II (Inngjerdingen et al, 2013), and unsaturated fatty acids (ximenynic acid) (Traore, 2008). These phytomolecules may be responsible of the antibacterial (Górniak et al, 2019;Lopes et al, 2017;Papuc et al, 2017) and antifungal (Merghache et al, 2012) activities of the plant extracts.…”
