The aim of the present study was to characterize the secondary metabolites and antimicrobial effect of six Indian
tropical fruit residues. Characterization of secondary metabolites was done by GC/MS while, antimicrobial effect
was evaluated by agar well diffusion method against five Gram-positive bacteria and four Gram-negative bacteria.
The results demonstrate that L. monocytogenes and S.aureus were more susceptible to all extracts followed by
other microorganisms. MIC of the all extracts was ranged between 4.1-6.9 mg ml-1. Among the all tested extracts,
the best antimicrobial activity was shown by C. carandas and A. lachoocha. GC/MS analysis showed the presence
of mainly essential oils such as aromatic phenolic compounds, fatty acids, sterols, alkaloids, alcohols and alkenes.
Result of the study shows that these residues can be further subjected to isolation of the therapeutic antimicrobials
and to further pharmacological evaluation.
