Abstract:
Medicinal plants constitute a rich and diverse source of biological components that have many uses in several fields, especially pharmaceutical ones. Under pure conditions, bacteria acquire resistance to some antibiotics. Therefore, we are interested in studying the effectiveness of five extracts from olive leaves from the Chemlal variety against seven pathogenic bacteria. As an antibacterial agent. Positive results have emerged, as acetate extract has a killing effect on Pseudomonas aeruginosa and Serratia Marcescens bacteria
Description:
Recently, the use of medicinal plants in herbal medicine has received great attention in biomedical research
The objective of this study is to study the antibacterial activity of the five extracts of olive leaves Olea europaea L. chemlal variety with increasing polarity: diethyl ether, chloroform ethyl acetate and n-butanol against seven strains. Wich they are :
• Citrobacter Freundii
• Streptococcus spp
• Klebsiella pneumoniae
• Proteus mirabilis
• Serratia Marcescens
• Escherichia coli
• pseudomonas aeruginosa
The acetate extract has a bactericidal activity in concentration of 0.1 Mg/ml against pseudomonas aeruginosa and, Serratia Marcescens and bacteriostatic effect against Escherichia coli and Streptococcus spp.
Aqueous extract :has a bacteriostatic activity against proteus.in all of the four Different
concentration According to these results, Aqueous extract can be used as an antimicrobial agent for proteus,Mirabilis
