Antibacterial Activities of Rambutan Peel Extract
Keywords:
antimicrobial, rambutan, tannins, phenolic componentsAbstract
The antimicrobial activities of the phenolic component containing rambutan (Nephelium lappaceum L.) extract are determined. The extract of rambutan pericarp possesses bactericidal activity against Staphylococcus aureus ATCC6538, methicillin-resistant Staphylococcus aureus (MRSA) DMST20645, and Streptococcus mutans ATCC25175T whilst no activity was found on gram negative bacteria Escherichia coli ATCC25922 and fungus Candida albicans ATCC10231 by agar disc diffusion assay. Due the rambutan pericarp extract displayed antimicrobial activity against S. aureus ATCC6538 and MRSA DMST20645 at diameter of the inhibition zone > 10 mm, tests of the minimal inhibitory concentration (MIC) of rambutan pericarp extract against S. aureus ATCC6538 and MRSA DMST20645 were further determined by broth microdilution assay resulting in 2 and 0.4 mg/ml, respectively.
