Abstract :
Securinega virosa (Roxb. ex Willd.) Baill. is a deciduous perennial shrub. The phytochemical and antimicrobial activity screenings of the leaf, stem, root, and blend (root+stem) extracts of the plant were carried out using standard techniques. Test of significance was measured using Duncan’s Multiple Range Test (DMRT). Alkaloids, flavonoids, phenols, tannins, terpenes, saponins, and sterols were detected in all the parts examined while hydrogen cyanide was found only in the leaf. The plant extracts exhibited a dose-dependent effects on the microorganisms tested. At 150 Mg/ml, the blend of stem and root extract had the highest inhibitory activities against Streptococcus agalactiae (6.27±0.04 mm), Salmonella typhi (5.77±0.04 mm) and Escherichia coli (5.74±0.02 mm) while the leaf extract had the highest level of inhibitory effects against Geotricum candidum (7.52±0.11 mm) and Aspergillus fumigatus (6.62±0.25 mm). The leaf, stem and root of S. virosa are endowed with phytochemicals that possess antimicrobial qualities, hence, suggesting their extraction for pharmaceutical applications.
