Study of Antibacterial Activity of Chenopodium album Leaves Extract

This study describes the antibacterial activities of three different solvent extracts of leaves of Chenopodium album. Methanol, acetone and chloroform extracts of C. album were prepared. The antibacterial activity was assessed using well plate method and were examined for the size of zone of inhibition. Different extracts were investigated against the test organisms namely Lactobacillus, Bacillus subtilis and Escherichia coli. The maximum activity was observed at 100% concentration of different extracts of leaves. The maximum zone of inhibition for 100% concentration were observed as E. coli (19 mm) and Lactobacillus (19 mm) in diameter respectively. C. album did not show any antibacterial activity against B. subtilis. Antibacterial activity was compared with standard Amoxicillin and it was found to be 23 mm diameter for Lactobacillus and 25 mm for both E. coli and B. subtilis in terms of zone of inhibition.
