Abstract
In the present study the antimicrobial activity of chloroform and methanolic extracts of Opuntiacochenillifera for both cladode and fruits was investigated. Methanolic extract was found to be an effective against the microbes namely, E. coli,Bacillus subtilis,Staphylococcus aureus, Pseudomonas aeruginosaCandidaalbicanC.glabrataC.haemuloniiC.Tropicalis. Maximum activity was observed against E. coli, B. Subtilisand,C.albican and C.glabrata at 40mg/ml. Agar well diffusion assay was used to determine minimum inhibitory concentration of all test microorganisms.
