Abstract: In this investigation, the antibacterial effects of
ethanolic and 7:3 isopropyl –hexane mixture extracts of Zingiber
officinale were evaluated against three Gram positive bacteria, B.
cereus, S.epidermidis, S. aureus and three Gram negative bacteria, E.
coli, K.pneumonia and P.areuginosa. Utilizing paper disk diffusion
and well methods in-vitro, MIC and MBC were determined by
macrodilution. The results showed that ethanolic rhizome extract of
ginger had significantly active than Isopropyl –hexan extract. Further
work needs to be done in these extracts including fractionation to
isolate active constituents and subsequent pharmacological
evaluation.
