초록

본 연구는 제주도에서 채집된 꿀풀을 꽃과 잎 부위별로 나누어 각 부위를 열수 추출하여 각 추출액을 농도별로 첨가하여 E. faecium KCCM 12118, L. rhamnosus KCCM 32826, L. plantarum KCCM 11542, P. pentosaceus KCCM 40464 균종에 대하여 생육에 미치는 영향과 그 배양액을 가지고 DPPH 라디칼 소거활성 및 Hydroxyl radical 소거활성 그리고 어류질병 미생물에 대한 항균활성을 조사하였다. 꿀풀의 꽃과 잎 추출액을 농도별로 첨가하여 4종의 lactic acid bacteria를 72시간 배양하면서 생육활성을 보았을 때 10%를 첨가하여 48시간 배양 하였을 때가 가장 좋은 생육조건임을 알 수가 있었으며, 또한 lactic acid bacteria 생육 시 꿀풀 꽃과 잎 추출액 첨가가 lactic acid bacteria 증식에 효과가 있음을 나타내었다. DPPH 라디칼 소거활성에서는 꿀풀 꽃 추출액을 10% 첨가하여 배양하였을 때 합성 항산화제인 BHA(90%)와 BHT(81%)의 EDA와 비교하였을 때 BHA와 유사하거나 조금 높은 활성을 BHT보다는 높은 라디칼 소거활성을 나타내었다. Hydroxyl radical 소거활성은 5% 꿀풀 각 부위의 추출액을 첨가한 배양액에서부터 BHT보다 높은 소거활성을 나타내기 시작하여 10%를 첨가한 배양액에서는 BHA보다 높은 소거 활성을 나타내었다.

In this study was investigated the growth effect of Prunella vulgaris. aleutica Fernald(leaf and flower) extracts on various lactic acid bacterias, electron donating ability and hydroxyl radical scavenging activity. The total cell count of Enterococcus faecium KCCM 12118, Lactobacillus rhamnosus KCCM 32826, Lactobacillus plantarum KCCM 11542, Pediococcus pentosaceus KCCM 40464 in the absence at $37^{\circ}C$ after 48hr were $2.2{\times}10^9\;cfu/ml,\;2.1{\times}10^9\;cfu/ml,\;2.3{\times}10^9cfu/ml,\;2.2{\times}10^9\;cfu/ml$. On the other hand, the total cell count of E. faecium KCCM 12118, L. rhamnosus KCCM 32826, L. plantarum KCC 11542, P. pentosaceus KCCM 40464 in the presence of Prunella vulgaris. aleutica Fernald(leaf and flower) extracts(10%) at $37^{\circ}C$ after 48hr were $4.3{\times}10^9-4.5{\times}10^9\;cfu/ml,\;4.3{\times}10^9-4.5{\times}10^9\;cfu/ml,\;4.8{\times}10^9-4.9{\times}10^9\;cfu/ml,\;4.1{\times}10^9-4.1{\times}10^9\;cfu/ml$. The electron donating ability indicated to E. faecium KCCM 12118, L. rhamnosus KCCM 32826, L. plantarum KCCM 11542, P. pentosaceus KCCM 40464 added by 10% Prunella vulgaris. aleutica Fernald(leaf and flower) extracts, respectively. when 10% native plant extracts were added lactic acid bacterias, the electron donating ability is the highest. Hydroxyl radical scavenging activity of L. plantarum KCCM 11542, L. rhamnosus KCCM 32826, E. faecium KCCM 12118, P. pentosaceus KCCM 40464 showed higher than that of control.
