Abstract

The aim of this research is to evaluate the potency of ethanol extract of several medicinal plants from North Sumatera as antimicrobial and its secondary metabolite composition was determined using qualitative and quantitative analysis. The antimicrobial was evaluated to Escherichia coli, (E. coli) ATCC25922 and Stapylococcus aureus (S. aureus) ATCC 25923 using ethanol extract of seven kinds of medicinal plant. The antimicrobial activity was determined by measuring the inhibitionzone of each extract. The phytochemical screening showed the extract contained some secondary metabolites, such as alkaloid, flavonoid, terpenoid, steroid, tannin and saponin. The medicinal plant extracts has a potency as antimicrobial, especially to E. coli ATCC 25922 and S. aureus ATCC 25923. Based on the inhibition zone, the extract inhibited E. coli ATCC 25922 better than S. aureus ATCC 25923.
