ABSTRACT
Finding natural antimicrobial compound with minimum side effects on health the is important because of microorganisms are more antibiotics resistance. Avicenniaceae family is a member of true mangrove plants which has one genus, 11 species and several sub species. Avicennia marina (Forssk.) Vierh is the most current species among these plants in Iranian mangrove forest. In this study, mangrove leaves were dried in shadow and appropriate condition. After extraction with ethanol 96 degree, methanol 96 degree and 20% glycerin antimicrobial effect of extract were determined by "screening antimicrobial activity" and "disk agar diffusion test" in 20, 40, 60 and 80 Percent concentration of the extract against Penicillium digitatum. The results showed that mangrove leaf extract in screening antimicrobial activity method in 2000 μg/ml, were inhibited Penicillium digitatum of growth. In "disk agar diffusion test, mangrove extract, in 20, 40, 60 and 80 Percent concentration, the mentioned extract were shown inhibition effect on mold pathogen growth. Ethanol 96 degree extract was more effective than methanol 96 degree and 20% glycerin extract as antimicrobial against on Penicillium digitatum (p
