 en PHYTOCHEMICAL AND ANTIBACTERIAL PROPERTIES OF PARKIA BIGLOBOSA AND PARKIA BICOLOR LEAF EXTRACTS
AJAIYEOBA, EDITH 0.

Abstract

The comparative studies of different extracts of the leaves of Parkia biglobosa check for this species in other resources (Jacq) Benth and Parkia bicolor check for this species in other resources A. Chev (Mimosaceae) with respect to their photochemical and antimicrobial properties was carried out. Preliminary phytochemical screening showed that both plants had similar constituents namely cardiac glycosides, steroids, tannins and alkaloids. The thin layer chromatography of the hexane and ethanol extracts of both plants were also investigated and two of the components of the ethanol extracts of both plants were found to display similar properties. The antimicrobial screening of the hexane, ethyl acetate, ethanol and water extracts of both plant leaves were done using standard strains of Staphylococcus aureus check for this species in other resources , Bacillus cereus check for this species in other resources , Esherichia coli check for this species in other resources , Pseudomonas aeruginosa check for this species in other resources , Aspergillus niger check for this species in other resources and Candida utilis check for this species in other resources . The ethyl acetate, ethanol and water extracts exhibited a concentration dependent antibacterial, inhibiting the growth of the gram-positive bacteria used in the study. Extracts of P. bicolor were slightly more active than those of P. biglobosa.
