The phytochemical screening of Hyophila involuta collected from the Biological Garden of the Obafemi Awolowo University, Ile-Ife, Nigeria, was carried out to investigate the presence or absence of some secondary metabolites and its antibiotic potentials, using different extracts (with acetone and ethanol) on selected organisms. The extracts obtained were screened for the presence of secondary metabolites like alkaloids, anthraquinones, cardiac glycosides, flavonoids, phlobatanins, saponins, steroids, tannins, triterpenes and xanthoproteins. Antimicrobial activity of the extracts was carried out on Escherichia coli , Staphylococcus aureus , Aspergillus flavus and Candida albicans. Only acetone extract tested positive for the presence of flavonoids, while alkaloids and cardiac glycosides were detected present in both the acetone and ethanolic extracts. Flavonoids were detected present only in the acetone extract. Saponins were detected present only in the ethanolic extract. The extracts (acetone and ethanolic) showed significant activity on Staphylococcus aureus and Aspergillus flavus. The results obtained from this study indicated that H. involuta has medicinally important compounds, having therapeutic potential from which effective antimicrobial medicine can be sourced.
