Investigation of Antimicrobial Activities of Extracts of Some Plant Sources Prepared in Different Solvents

In the present study, it was aimed to research the antimicrobial activities of prepared extracts of some plant sources such as aloe vera (Aloe barbadensis), marigold (Calendula officinalis), maidenhair fern (Adiantum capillus-veneris Linn.) and bitter melon (Momordica charantia) by using different solvents. For this purpose, the extracts of the plants in the solvents as n-hegzan, ethanol, methanol and distilled water were prepared via maceration process. Either antibacterial activies against Staphylococcus aureus and Escherichia coli or antifungal activities against Aspergillus niger of the prepared extracts were investigated. The results demonstrated that the plant sources and solvent types used in the extraction are crucial on the antimicrobial activities of the extracts.
