|Abstract: ||The phytochemical analysis, elemental analysis, antimicrobial activities and the minimum
inhibitory concentration (MIC) of aqueous and ethanolic extracts of the leaves of Cassia arereh
Del. were carried out. Phytochemical investigation revealed the presence of several bioactive
compounds such as alkaloids, flavonoids, anthraquinones, saponins, glycosides, tannins,
carbohydrates and terpenes. Elemental analysis revealed the presence of calcium (Ca),
phosphorus (P), Manganese (Mg), Manganese (Mn), Iron (Fe), Copper (Cu) and Zinc (Zn).
Manganese was present at a higher concentration (11.50 μg/g) followed by Zinc (3.35 μg/g).
Antimicrobial studies showed that the ethanolic extract had considerable inhibitory activity
against Staphylococcus aureus, Streptococcus pyogen, Salmonella typhi, Shigella dysentery
and Eschenchia coli. Ethanolic extract had higher zone of inhibition (32 mm) against salmonella
typhi at (0.5 μg/ml) with minimum inhibitory concentration (MIC) value of 8 x 102 μg/ml. The MIC
ranges from 4 x 102 μg/ml to 5 x 104 μg/ml for other bacteria.|
