This study was carried out to assess anticariogenic activity from natural products. The hexane extracts of 11 medicinal plants were tested for the antimicrobial activities against a cariogenic bacterium, S. sobrinus B13. The hexane extracts of 11 medicinal plants such as Alisma orientale, Cyperus rotundus, Saussurea lappa, Atractylodes japonica, Kalopanax pictus, Angelica gigas, Salvia miltorrhiza, Lonicera japonica, Gardenia jasmoides, Aurantii nobilis percarpium and Bupleurum lorgiradiatum were used for this study, and S. sobrinus B13 was cultured with 0.5% extracts of the medicinal o plants, in trypticase soy broth medium under 5% CO for 0, 6, 12, 24 hours at 37 C. The obtained results were as follows. 2 Immediately after culturing for inoculation, Kalopanax pictus and Cyperus rotundus showed better antimicrobial activities than those of others. After culturing for 6 hours, the order of effective antimicrobial activity was Salvia miltorrhiza, Angelica gigas. After incubation for 12 hours, Salvia miltorrhiza showed the best antimicrobial activity. After incubation for 24 hours Salvia miltorrhiza, Cyperus rotundus, Saussurea lappa, Atractylodes japonica had better antimicrobial activity than others. In conclusion, among Hexane extracts of 11 medicinal plants, Cyperus rotundus, Saussurea lappa, Atractylodes japonica showed effective antimicrobial activity.
