ABSTRACT
The antibacterial potential of the leaf and flower extracts of anthurium (A. andraeanium), sunflower (H. annus), birds of paradise ( S. reginae), bougainvillea (B. glabra), chrysantheum (C. morifolium), and French rose (R. gallica) were tested against B. subtilis and S. aureus using disc diffusion method.
The diameter zone of inhibition after incubation was measured. The Tukey test was used to se if the antibacterial potential of the extracts vary significantly. The result showed tetracycline as having the highest diameter zone of inhibition against B. subtilis and S. aureus.
The means of the diameter zone of inhibition of leaf extracts against B. subtilis decreased in the order: tetracycline > French rose > birds of paradise > anthurium > chrysanthemum > bougainvillea > sunflower = distilled water.
The means of the diameter zone of inhibition of the flower extracts against B. subtilis decreased in the order: tetracycline > French rose > birds of paradise > anthurium > sunflower. bougainvillea > chrysanthemum = distilled water.
The means of the diameter zine of inhibition of the leaf extracts against S. aureus decreased in the order: tetracycline > French rose > birds of paradise > anthurium > chrysanthemum > bougainvillea > sunflower = distilled water.
