| Abstract |
|
Recently interesting in development of antimicrobial agent from natural origin has been increased in these days. Many studies have been reported antimicrobial effect of Horseradish(Armoracia rusticana) root extracts against various microorganisms such as Escherichia coli, Salmonella typhimurium, Pseudomonas aeruginosa, Vibrio parahaemolyticu, Staphylococcus aureus, Bacillus subtilis, Aspergillus parasiticus, Helicobacter pylori. The main component related to antimicrobial activity in horseradish is well known as allyl isothiocyanate(AIT). In this study, we investigated the antimicrobial effects of Horseradish(Armoracia rusticana) root extracts against Streptococcus mutans isolated from human dental plaque, Streptococcus mutans reference strain and compared with that of chlorhexidine. Horseradish root extracts and chlorhexidine were tested to determine their minimum inhibitory concentration( MIC) and minimum bactericidal concentration(MBC). The result of this study can be summerized as follows; 1. Horseradish root extracts showed antimicrobial effect against both S. mutans isolated strain and reference strain, their MIC were respectively 0.083~0.25% (833.33~2500 ppm), 0.25% (2500 ppm). Horseradish root extracts showed antimicrobial effect against S. mutans isolated strain at same or slightly lower concentration compared with MIC of reference strain. 2. 0.083~0.25% horseradish root extracts showed similar antimicrobial effect with chlorhexidine (0.0021~0.0041%). |
