Antibacterial activity and GC-MS analysis of ripened and unripened banana (Musa x paradiscia L) cv. chakkarakeli fruit pulp extracts

[摘要] Anti bacterial activity and minimal inhibitory concentrations (MIC )of ripened and un ripened aqueous, ethanolic, methanolic and hexane fruit pulp extracts of Musa x paradisiaca L cultivar chakkarakeli against pathogenic bacteria Escherichia coli, Pseudomonas aeruginosa, Bacillus cereus and Micrococcus flavus were investigated. Different ripened and un ripened chakkarakeli banana extracts showed broad inhibitory activities towards pathogenic micro-organisms. Ethanolic extracts showed good activity compared to other extracts with respect to similar bacteria. GC-MS analysis of ripened methanolic pulp extract showed the presence of several bioactive compounds like aldehydes, ketones, alcohols, furans , sulphur compounds , pyrimidines, nitrosamines, esters, eugenol and sugars that may be responsible for medicinal actions of bananas.
