ABSTRACT: Known for their role in the manufacture of
eco-materials in buildings, Parkia biglobosa fruit husks are also used
in folk medicine. The present study focuses on the metabolites content and
antiradical, antibacterial activities of the hydroethanolic extract of P.
biglobosa husks. Secondary metabolites were identified using staining
and/or precipitation tests. The mineral content is determined according to the
standard NF EN 14082. The antioxidant activity performed by
2,2-diphenyl-1-picrylhydrazyl (DPPH) scavenging capacity, and antibacterial
activity strain against three Gram-negative and two Gram-positive strains by
microdilution for Minimal Inhibitory Concentration. Fruit husks contain
tannins, anthocyanins, leuco-anthocyanins, anthraquinones, saponins, reducing
compounds, sterols, terpenes, and 1.225% of potassium. The hydroethanolic
extract of P. biglobosa fruit husks scavenges the DPPH radical with an
EC50 = 64 μg/ml. The extract is more active in one Gram (Pseudomonas aeruginosa and Escherichia
coli) with a minimum inhibitory concentration of 1.25 mg/mL than the three
Gram + studied. This study showed that P. biglobosa fruit husks extract
could be used for its antioxidant and antibacterial activities.
