ABSTRACT

            Guava (Psidium guajava L) is native to South America and exists as both wild and cultivated. Guava has been used as a source of food and raw materials for pharmaceuticals. The aim of this study was to determine bioactivity of methanol and water extracts from apple guava against selected pathogenic bacteria. Study samples were collected from Tal, Gombe State, Nigeria and taken to the departmental herbarium for identification to obtain voucher number. Fifty grams of fruit ground powders were used for sequential extraction using methanol and aqueous. Extracts were evaporated and stock solutions were prepared, out of which concentrations of 12.5mg/ml, 25gm/ml, 50gm/ml, and 100mg/ml were prepared. Phytochemical screening conducted revealed the presence of Tannins, Saponins, Steroids, Glycoside, Phlobatannins, Resins, Phynols, Alkaloid, Anthraquinone, Flavaloid while terpenoid was absent in both aqueous and methanol extracts. Antibacterial activities were recorded underconcentration of 100mg/ml, 50mg/ml, 25mg/ml, and 12.5mg/ml respectively for methanol and aqueous extracts. The zones of inhibition were recorded 12mm, 10mm, 8mm, and 6mm on S. aureus while 10mm, 8mm, 6mm, and 4mm were recorded on E.coli methanol extract.zones of inhibition under aqueous extract was 10mm, 8mm, 6mm and 4mm for S.aureus while 8mm, 6mm, 4mm, and 2mm respectively recorded for Ecoli.  Minimum inhibitory concentration (MIC) and minimum bacteriacidal concentration (MBC) was determined.
