| Abstract:
Seven herb and spice extracts of Allium cepa (onion), Allium sativum (garlic), Areca catechu (betel nut), Capsicum frutescens (chili), Psidium guajava (guava), Mentha cordifolia (mint) and Alpinia galanga (galangal) were chosen to screen for antibacterial activity against eight strains of Gram-positive and Gram-negative bacteria using a disc-diffusion method. Garlic extract exhibited an inhibition effect against five strains whereas guava and betel nut extracts showed antibacterial activity against four strains. Further studies showed that the minimum inhibitory concentration (MIC) of garlic, guava and betel nut extract against bacteria was ranging from 62.5-500 mg/ml. These results showed that herb and spice extracts may prove useful in inhibiting bacteria. | |
