Abstract

This study was conducted to assess the antimicrobial activity of the stem juice (sap) and the extracts of the Jatropha spinosa, that belongs to the Euphorbiaceae family. The stem juice and the methanoli stem extract were tested against three bacterial species and one fungi. They are as follows: the Staphylococcus aureus, Escherichia coli, Pseudomonas aeruginosa and candida albicans was also used via agar diffusion and minimum inhibitory concentration of (MIC) as a determination method. The fresh stem juice and the mehanolic stem extract displayed a potential antibacterial activity against all the bacterial species, but the stem juice was more effective than the methanolic stem extract. The plant extracts not showed any efficiency on C. albicans. MIC values for all the existing extracts at a concentration of 25 μl and 5 mg/l.
