1Antibacterial activity and characterization of secondary metabolites isolated from mangrove plant Avicennia officinalis显示文摘Objective:To explore antibacterial activity and characterization of secondary metabolites isolated from mangrove plant Avicennia officinalis(A.officinalis).Methods:In the present study the leaf extracts of A.officinalis were examined for its antibacterial potential using five different solvents against some reference strains of human pathogenic bacteria for the crude extract.Maximum activity was observed for ethyl acetate and hence different concentrations like 15μL,25μL,and 50μL of ethyl extracts was checked for its antibacterial activity.Partial purification of crude extract was carried by column chromatography and fractions were analyzed using gas chromatography-mass spectrometry(GC-MS) to identify compounds.Results:The crude ethyl acetate extracts of A.officinalis showed remarkable antibacterial activity with zones of inhibition of 13 mm against Eschericia coli(E.coli) and 11 mm against Staphylococcus aureus (S.aureus).Fraction 13(ethyl acetate:methanol= 8:2) as the most potent one against with the minimal inhibitory concentration of 30 mm against E.coli and 25 mm against S.aureus.The GCMS resultsof active column fraction(F13) revealed that the active principals were a mixture of hydroxy- 4 methoxybenzoic acid,diethyl phthalate,oleic acid.Conclusions:The leaf extracts with proven antibacterial effects can clearly be directed towards cancer treatment as to inhibiting cancer cell growth.The limited number of test organisms owes to a constraint of resource.So,the effect of strong bursts of leaf extracts on human pathogenic bacteria should further be tested on a wide range of test organisms.Valentin Bhimba B J Meenupriya Elsa Lycias Joel D Edaya Naveena Suman kumar M Thangaraj 2010Asian Pacific Journal of Tropical Medicine2010,3,7:13
