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