Antimicrobial Activities of Extracts of Some Species of Mangrove Plants and a New Compound Isolated Towards some Selected Strains
نویسندگان
چکیده
The bio-materials of four marine mangrove medicinal plants viz., Aegiceras Corniculatum (AGC), Excoecariaagallocha (EA), Rhizophoramucronata (RM) and Xylocarpusgranatum (XG) are extracted with methanol and hexane. These extracts are submitted to the antibacterial activity towards the strains:Bacillus puvuilis, Bacillus subtilis, Bacillus coagulans, Staphylococcus aureus, Bacillus licheniformis, Corynebacterium diphtheria, Klebsiella pneumonia, Pseudomonas aeruginosa, Shigellaflexneri, Sphingomonaspaucimobilis, Escherichia coli and Vibrio choleraadopting Agarwell diffusion method. It is found that a new Flavone Compound isolated from hexane extract of EAis effective towards Bacillus puvuilis, Bacillus subtilis, Bacillus coagulans, Staphylococcus aureus, Bacillus licheniformis, Corynebacterium diphtheria, Klebsiella pneumonia, Pseudomonas aeruginosa, Shigellaflexneri, Sphingomonaspaucimobilis, Escherichia coli and Vibrio cholera strains while RM MeOH extract is effective towards the strains Bacillus puvuilis, Bacillus subtilis, Bacillus coagulans, Staphylococcus aureus, Bacillus licheniformis,Corynebacterium diphtheria, Klebsiella pneumonia, Pseudomonas aeruginosa, Shigellaflexneri, Sphingomonaspaucimobilis, Escherichia coli and Vibrio cholera. The XG MeOH extract is found to be effective towards the strains Bacillus puvuilis, Bacillus subtilis, Bacillus coagulans, Staphylococcus aureus, Bacillus licheniformis, Corynebacterium diphtheria, Klebsiella pneumonia, Pseudomonas aeruginosa, Shigellaflexneri, Sphingomonaspaucimobilis, Escherichia coli and Vibrio cholera strains while AGC MeOH extract is found to be effective towards the strainsBacillus puvuilis, Bacillus subtilis, Bacillus coagulans, Staphylococcus aureus, Bacillus licheniformis, Corynebacterium diphtheria, Klebsiella pneumonia, Pseudomonas aeruginosa, Shigellaflexneri, Sphingomonaspaucimobilis, Escherichia coli and Vibrio cholera.The order of effectiveness is found to be: EA Hexane > RM MeOH> XG MeOH> AG MeOH. Finally a new flavone compound is found to be more effective than the extracts.
