Phytochemical screening of the bark of Chlorophora excelsa (WELW.) BENTH and HOOK F

Abstract

 Phytochemical screening of the bark extract showed the presence of carbohydrates, and saponins.
 Cytotoxic test using brine shrimps (Artemia salina) lethality assay was carried out on methanol,
 petroleum ether [60-800C] and ethylacetate extracts. The LC50 (lower-upper limits) obtained by the
 Finney computer programme were 54 µg/ml [9.90 – 100.70 µg/ml], 165 µg/ml [117.58 – 217.42 µg/ml]
 and 63µg/ml [34.03 – 87.77 µg/ml] respectively at 95% confidence interval and 3 degrees of freedom.
 Antimicrobial sensitivity tests of the same extracts were carried out on microorganisms such as
 Escherichia coli, Staphylococcus epidermis, Salmonella and Candida albicans.
