Phytochemical screening and Antimicrobial Assessment of Extracts of the pods of Parkia biglobosa (Jacq.Benth),

Abstract

The phytochemical screening and antimicrobial assessment of the extracts of the pods of Parkia biglobosa were investigated. Qualitative photochemical analysis revealed the presence of active principles such as the tannins, anthraquinones, flavonoids, saponins, steroidal nuclei, combined reducing sugar, reducing sugar, carbohydrates, cardiac glycosides and alkaloids, mostly in the aqueous and ethanolic extracts, although the petroleum ether extract was positive for Salkowskii and Liebermann - Burchard's tests. The antimicrobial tests indicated that both the aqueous and the ethanolic extracts were strongly active against Salmonella typhi, Pseudomonas aeruginosa, Staphylococcus aureus, Escherichia coli, Streptococcus pygenes and Proteus vulgaris. These results showed that this plant pods could be a potential source for new antimicrobials against enteric organisms.
