Antioxidant and antibacterial activities of various extracts of Inula cuspidata C.B. Clarke stem

All the extracts showed significant antibacterial activities against Gram positive bacterial strains with minimum inhibitory concentration (MIC) values ranging from 187.5 to 750 µg/mL and moderate to weak inhibition against Gram negative bacteria with MIC values ranging from 750 to 3000 µg/mL. The present study proves the in vitro anti-oxidant and antibacterial activities of different extracts of I. cuspidata stem.
