Extracts drawn from dried and powdered flowers, of Calotropis procera with some organic solvents and aqueous were tested for antimicrobial effect against the fungi, Cladosporium sp., Mucor sp., Aspergillus flavus and Fusarium oxysporum. Methanol was the best solvent to extract antimicrobial compounds from flowers and was superior to chloroform, water and petroleum ether. The strongest inhibitory effect of the extracts was observed against Cladosporium sp., Mucor sp. The weakest effect was against Fusarium oxysporum. Results clearly indicate that the flowers of Calotropis procera is a promising source of antimicrobial compounds.
