Abstract

Fourteen phenolic compounds(benzoic acid, p-hydroxybenzoic acid, protocatechuic acid, vanillic acid, syringic acid, gallic acid, caffeic acid, ferulic acid, (+)-catechin, quercetin, rutin, catechol, chlorogenic acid and L-ascorbic acid) were examined for their effects on the anticarigenic activity. Among tested samples, catechol was significantly inhibited the S. mutans, exhibiting an clear zone 18.5-19.5mm by 10 mg/disc level. The minimal inhibition concentration(MIC) of the phenolic compounds for Streptococcus mutans, M1 and M2 strain were determined as 2,000 ppm, whereas catechol was 1,000 ppm. The activity of glucosyltransferase(GTase) was significantly inhibited by catechol, at 10 ppm(58.7%), 50 ppm(60.7%) and 100 ppm(88.4%) and 500 ppm(89.6%), respectively. Among them, catechol showed most significant anticariogenic activity as well as inhibition of GTase activity.

충치원인균인 Streptococcus mutans에 대한 페놀성 화합물(14종)의 항미생물활성은 hydroxybenzoic acid group에서는 syringic acid를 제외한 모든 화합물이 5와 10 mg/disc 함유량에서 $8.5{\sim}18mm$까지의 생육저해환을 나타내었다. 기타 phenolics 화합물에서는 catechol과 L-ascorbic acid가 저해능을 나타냈는데, 특히 catechol은 10 mg/disc 함유량은 $18.5{\sim}19.5mm$로 강한 항미생물활성을 나타냈다. Phenolic compounds의 최소저해농도는 S. mutans, M1 및 M2 균 모두에서 2,000 ppm의 농도에서 MIC 값을 나타내어 큰 차이를 보이지 않았으며, catechol만 1,000 ppm의 농도에서 높은 MIC 값을 나타내었다. 충치 관련 미생물인 S. mutans에 대해 항미생물활성이 인정된 7종의 페놀성 화합물을 대상으로 S. mutans가 생산하는 glucosyltransferase(GTase)의 활성저해능은 benzoic acid와 p-hydroxybenzoic acid 처리구에서는 100과 500 ppm 농도에서 약하게나마 GTase활성을 저해하는 경향을 나타냈으며, gallic acid 처리구는 10 ppm부터 활성을 나타내기 시작해서 100 ppm과 500 ppm에서 약 50%의 저해 활성을 나타냈다. 한편 catechol 처리구에서는 10 ppm에서 58.7%의 저해활성을 나타내었고, 50 ppm에서 60.7%, 100 ppm에서 88.4%, 그리고 500 ppm에서 89.6%의 높은 활성을 나타내어 catechol의 S. mutans에 대한 생육저해능 측정에서 높은 항미생물활성을 나타낸 결과와 동일한 경향을 나타냈다.
