Abstract

Cydonia Oblonga seeds were assessed for Phytochemicals. The results showed that the extract of the seeds possessed tannins, glycosides and phenolic compounds. The antibacterial activity of the seeds extract was assayed against Staphylococcus aureus, Staphylococcusepidermids, Klebsiellapneumonia, Escherichia coli and Moraxella using the agar well diffusion method. The extract exhibited antibacterial activity, Staphylococcus aureus was the most susceptible to the plant seeds extract while Escherichia coli and Moraxella were the most resistant. In conclusion, Cydonia Oblonga seeds had potential antibacterial activity against gram-positive bacteria more than gram-negative bacteria.
