Abstract

Pet ether and Ethanol solvent was used to extract the roots, stem-bark and leaves of three indigenous plant Alstonia boonei, Mimosa pudica and Sansevieria transfica locally reputed for their treatment of asthma. Ethanol has higher % of extract. The extract were phytochemically screened and tested for their biological activity against Staphylococcus aureus (bacteria) and Aspergillius niger (fungi). The phytochemical test showed that both the ethanol and petroleum ether extracts contain bio-active agent. The petroleum ether extracts of Alstonia boonei, Sanseviera transfica and Mimosa pudica shows inhibition zones against staphylococcus aureus and Aspergillus niger.
