In the present study, an antimicrobial activity of some higher plant floral petal extracts were tested against the gram positive and gram negative bacterial strains, Bacillus subtilis, Bacillus megatherium, Staphylococcus aureus, Escherichia coli and Proteus vulgaris respectively. The floral petal extracts showed different degree of inhibition zones against tested microorganism. Off 14 plants floral extracts only 9 plants petals exhibited antibacterial activity against tested micaroorganisms. Among nine only four plants extracts viz. Nerium indicum, Celosia cristata, Cocinia indica and Cucurbita maxima showed higher antibacterial activity.
