Abstract

The antimicrobial activity of aqueous and methanolic extracts of Emblica officinalis seeds were tested on different microbial pathogens.The zones of inhibition ranged between 6mm to 16mm for bacterial pathogens and 6mm to 24mm  for fungal pathogens.The aqueous extract showed zones of inhibition only for E.coli and Candida albicans. The cold methanol extract showed zones of inhibition ranging from 0.0mm to 12mm, with maximum activity against   Geotrichum and Fusarium and minimum activity against Salmonella typhimurium. The zones of inhibition to distillate and residual extract ranged between 0.0mm to 17mm and 0.0mm to 24mm respectively suggesting that the residual extract was more effective than aqueous, cold methanol and distillate extracts. The MICs ranged from 50 µg/ml to 800 µg/ml indicates that A.flavus was more sensitive as it showed less MIC. There results showed that seeds of Emblica officinalis extracts possess potent antimicrobial activity.
