Abstract

Abstract:

Antibacterial activities of water extract (PWE) and alcohol extract (PAE, 70g/100mL ethanol) from Clematis songarica Bge. were evaluated. Results indicated that minimum inhibition concentrations (MICs) of PWE from leaves were 5g/100mL for Echerichia coli, 3g/100mL for Staphylococcus aureus and Bacillus pumilus, and 1g/100mL for Bacillus subtilis. MICs of PAE from leaves were 3g/100mL for Echerichia coli, 0.5 g/100mL for Staphylococcus aureus and Bacillus subtilis, and 1 g/100mL for Bacillus pumilus. MICs of PWE from stems were 10 g/100mL for Echerichia coli, and 7 g/100mL for Staphylococcus aureus, and 5 g/100mL for Bacillus pumilus and Bacillus subtilis. MICs of PAE from stems were 7g/100mL for Echerichia coli, 5 g/100mL for Staphylococcus aureus, and 3 g/100mL for Bacillus subtilis and Bacillus pumilus. MICs of PWE from flowers were 5 g/100mL for Echerichia coli, 3 g/100mL for Staphylococcus aureus and Bacillus subtilis, and 1g/100mL for Bacillus pumilus. MICs of PAE from flowers were 1 g/100mL for Echerichia coli, Staphylococcus aureus and Bacillus pumilus, and 0.5 g/100mL for Bacillus subtilis. MICs of PWE from fruits were 5 g/100mL for Echerichia coli and Bacillus pumilus, and 3 g/100mL for Staphylococcus aureus and Bacillus subtilis. MICs of PAE from fruits were 3 g/100mL for Echerichia coli, and 1g/100mL for Staphylococcus aureus, Bacillus pumilus and Bacillus subtilis.
