ABSTRACT
Pimenta dioica (Linn.) Merill (family: Myrtaceae) is commonly known
as Allspice, Pimenta, Pimento, Clove pepper and Jamaica pepper. The
aim of the present study was to determine antibacterial activity of
methanolic extract of leaf and bark of P. dioica. Inhibitory effect of
leaf and bark extracts was determined by agar well diffusion assay
against clinical isolates of Staphylococcus aureus and Streptococcus
mutans recovered previously from burn and dental caries patients
respectively. The extracts were found to be effective in inhibiting test
bacteria. S. mutans isolates were highly susceptible to extracts when
compared to S. aureus isolates. The potential of extracts to inhibit
clinical isolates of bacteria could be attributed to the presence of
inhibitory components that are present in the extracts. The plant can be
a potential candidate for the development of agents active against
pathogenic bacteria.
Keywords: Pimenta dioica, Allspice, Agar well diffusion, Dental caries, Burn.
