Antibacterial efficacy of amla leaves

Abstract

The present study was carried out to evaluate antibacterial potential of methanolic extract from amla leaves via agar-well diffusion method against two gram positive ( subtilis MTCC2389, MTCC7443) and three gram negative (MTCC4821, MTCC2127, MTCC7162) strains. Susceptibility of plant extract was tested by serial microdilution method (MIC) and agar well diffusion method was determined. The extract showed maximum zone of inhibition against (17.6 mm) followed by (16.5 mm) and (16.2 mm). However, activity was also reported against (15.5 mm) and (15 mm). The different concentrations of extract (10μl and 20μl) were used and the minimum inhibitory concentration (MIC) ranging from 62.5 to 2000 μg/ml was compared with the standard drug Chloramphenicol (5μg). The MIC of methanolic extract was found 550 μg/ml against and The results of present study revealed that leaves of amla possesses antibacterial potential and source of new antibiotics. Therefore, medicinal plants are finding their way into pharmaceuticals, neutralceuticals and food Supplements that could be useful in chemotherapy to control infectious diseases.
