초록

버섯류는 기호식품으로서의 성격과 기능성식품으로서의 성격을 동시에 갖는 매우 독특한 식품소재로서 본 연구에서는 국내에서 자생하는 8종류의 버섯에서 항충치 활성성분을 조사해 보았으며, 더불어 높은 항충치활성을 가진 추출물을 얻고자 다양한 용매를 이용, 최적의 용매조성을 탐색해 보았다. Chloroform, methanol, acetone, ethyl acetate 및 증류수를 용매로 사용하였으며, 이들 추출물의 S. mutans에 대한 항균 효과와 glucosyltransferase (GTase) 활성 억제효과를 살펴보았다. 표고버섯, 영지버섯 및 만가닥버섯 추출물이 상대적으로 높은 항충치활성을 나타내었으며, 추출용매에 의한 항균효과를 조사해본 결과, chloroform, methanol, ethyl acetate로 추출한 버섯 추출물에서 상대적으로 높은 항균효과를 보여주었다. 8종의 버섯 중 항균효과가 뛰어나고 GTase 활성 억제효과가 높은 만가닥(Lyopyllum ulmarium) 버섯으로부터 chloroform, methanol 및 ethyl acetate 추출물을 얻어 항충치활성을 조사하였다. S. mutans에 대한 만가닥 버섯의 최대 항균효과를 얻기 위해 심플렉스 중심 합성 계획법(simplex centroid design)을 이용하여 최적의 추출용매조성을 살펴본 결과, chloroform, methanol 및 ethyl acetate 3가지 용매를 모두 동일한 비율(1:1:1)로 혼합하여 추출한 추출물에서 가장 높은 항균효과가 나타났다. 만가닥버섯추출물은 항충치 소재로서 중요한 역할을 할 수 있을 것으로 기대되며, 버섯추출물의 항충치 효과는 추출용매에 의해 영향을 받으므로 버섯에서 항충치활성물질을 얻고자 할 때에는 추출용매선택이 매우 중요할 것으로 사료된다.

Various mushroom extracts were examined for their anti-Streptococcus mutans and anti-glucosyltransferase (GTase) activities. Mushrooms were extracted with chloroform, methanol, acetone, ethyl acetate, and distilled water. The chloroform, methanol, and ethyl acetate extracts showed higher antimicrobial activity than that of the others. The inhibitory effects of the chloroform, methanol, and ethyl acetate extracts of Lyopyllum ulmarium, which have high anti-microbial and GTase activities, on the growth of S. mutans were examined and the optimal ratio of solvents was also evaluated to investigate the influence of solvents using a simplex centroid design. The anti-cariogenic effects of the L. ulmarium extract on S. mutans was influenced by the solvent, and the optimum anti-cariogenic activity of the extract was obtained with the ratio of chloroform:methanol:ethyl acetate=1:1:1 (v/v/v). These results suggest that solvent selection is an important factor to extract anti-cariogenic materials effectively from mushrooms.
