【 摘 要 】

Schinus molle L., an ornamental plant of the Jordanian environment, was acknowledged recently for its therapeutic properties against many microbes. This study aimed at evaluating the antibacterial potential of the ethanolic and methanolic extracts obtained from different parts of the Schinus molle L. tree against four strains of bacteria. Data in this study showed that, the ethanolic and methanolic extracts from all experimented plant parts inhibited the growth of Bacillus subtilis successfully. However, the best results were obtained from the ethanolic extract of leaves as it resulted in a growth inhibition zone of (22.0 ±0.06 mm), while growth was completely inhibited at MIC value of (1.563 mg/mL). Moreover, growth of Enterobacter aerogenes and Klebsiella pneumoniae were mostly inhibited after exposure to the methanolic extract of the leaves as it resulted in inhibition zones of (18.0 ±0.086 and 17.0±0.12 mm) respectively, while full growth inhibition was obtained at MIC being (1.563 mg/mL). Moreover, results of disc diffusion assay indicated that Micrococcus luteus growth was slightly affected by the leaves’ ethanolic extract, while all other types of either ethanolic or methanolic extracts failed to inhibit growth of these bacteria. However, the results of microdilution assay revealed a full growth inhibition of Micrococcus luteus when exposed to either fruit or leaves’ ethanolic extracts at level of (6.25 mg/mL). However, methanolic extracts from all invistigated plant parts faild to prevent the growth of Micrococcus luteus.
