Abstract

The aim of the present study was to determine the antimicrobial study of methanolic and ethanolic extracts of marigold/zendu (Marathi) (Calendula officinalis linn.) petals against gram-positive and gram-negative pathogens. The antimicrobial study of C. officinalis extracts has been evaluated by disc diffusion method against number of bacteria and methanolic extract of C. officinalis exhibited better antibacterial activity against most of the bacteria tested, than ethanolic extract. Both methanol and ethanol extracts showed excellent antimicrobial activity against tested strains of bacteria, while comparing with ciprofloxacin.
