L. ROMAN, A. HOSU, C. VASILIU, H. ROMAN, Gh. CIUCÄ, G. MIHÄESCU Conclusions Hydroethanolic extract of Juglans nigra, had a very good activity against phytopathogens Gram positive and Gram negative strains. Although phytopathogens are specific of plants, however they may have harmful effects on the human body. The mode of action of phytopathogens remain an area of study, too little is known of their mechanisms of action that may have repercussions on the human body, with reference, especially to persons who from different reasons, due to their field activity, are in permanent contact with wooden objects which are subject to bacterial attack. The importance of finding herbal extracts with wide spectrum antibacterial activity is reflected by the ease of obtaining them but especially by specific action against pathogenic microorganisms which proved to be not infrequently severely, most often with irreversible implications. The antibacterial activity of the hydroethanolic extract of J. nigra was due to role of metabolic synthesized compounds which acts in concert against pathogens bacteria. As a general conclusion, hydroethanolic extracts of J. nigra, can be successfully used both to prevent bacterial attack and for its invasion. REFERENCES 1.
