Abstract
The current study included the preparation of the aqueous and alcohol extract of leaves of Ziziphus (Ziziphus spina-christi) and Eucalyptus plant (Eucalyptus camaldulensis) and assessed its antimicrobial activity against reference strains of bacteria and mold. The chemical compound detection Ziziphus leaves results showed that the aqueous extract and alcohol contain all effective compounds that have been detected except composite resin extracts. The Eucalyptus leaves aqueous and alcohol extract contained resins, tannins, phenols. It was tested the effectiveness of inhibitory plant extract against five isolates of bacteria and molds. It uses concentration of 50 and 100 mg/ml of each extract. A Similar maximum zone of inhibition through alcoholic extract was obtained against both bacterial and mold isolates as well as increased efficiency as dose dependent fashion.
