Antibacterial Activity of Naphthalin and Its Derivatives against Oral Bacteria

摘要

Naphthalin derived from the essential oil of Magnolia liliflora was tested for antibacterial activity against oral bacteria. Naphthalin showed strong growth inhibitory activity against Actinomyces viscosus and Streptococcus salivarius, and exhibited moderate or weak growth inhibitory activity against Pophyromonas spp. and Streptococcus spp. at 2.0 mg/disc, whereas Lactobacillus rhamnosus showed no growth inhibition. Therefore, M liliflora could be useful as a natural preventive agent.
