Methanolic extracts inhibited zones exhibited antibacterial activity on various pathogenic bacteria (Table 15& Fig 20). Antibacterial activity test of methanolic extract on 4 bacterial strains (Staphylococcus aureus, E. coli, Strepneumonia and Pseudomonas aeruginosa) against ampicillin as a standard. The values of ampicillin and methanolic extract are all in microgrammes whilst the zones of inhibition are in millimetres.

For instance, with respect to Staphylococcus aureus; for both ampicillin and the methanolic extract, the zone of inhibition increased with increasing concentration as observed. Ampicillin: Zones 20 mm > 21 mm > 22 mm >23 mm Methanolic extract: Zones-10 mm,13mm,16mm,18mm For E. coli too, the zones of inhibition increased with increasing concentrations for both articles. Ampicillin showed 17 mm, 18 mm, 20 mm and 21 mm zones whereas methanolic extract exhibits 9 mm, 13 mm,16mm, and with hindrance of antibiotic zone-18mm.
