Abstract:
Background: Wastewaters generated from ubiquitous use of water in daily human activities often contains various pathogenic microorganisms, which may contaminate surface or ground waters when released indiscriminately into the environment. Consumption of natural water resources polluted by such contaminated wastewaters may compromise public health and decrease the populations of aquatic organisms in such water bodies. Mangifera indica (mango) plants have been widely used as remedy for treatment of a wide range of water borne ailments. This study was therefore conducted to identify bacteria contaminating wastewaters from domestic sources and to determine the antibacterial potentials of mango bark and leaf extracts against them.

Evaluation of Sida acuta subspecie acuta leaf/flower combination for antimicrobial activity and phytochemical constituents

Alhaji Saganuwan Saganuwan, Gulumbe Mohammed Lawal

 

Abstract

Sida acuta subspecie acuta Ieaf/flower combination was evaluated for antimicrobial activity and phytochemical constituents using methanol, hexane, chloroform and aqueous method of extractions. The antibacterial activities were exhibited by the four extracts on E. coli, S pyogenes, P.multocida and S. typhumrium as there was no activity exhibited on S. tyhi, S. pneumoniae and K. phneumoniae. Phytochemical analyses revealed the presence of alkaloid, tannin, flavonoid and saponin whereas steroid and glycoside were absent.
