Abstract

Paeonia lactiflora Pall. was extracted with water and the Paeonia lactiflora Pall. extract (PLE) was tested for antimicrobial activities against Corynebacterium xerosis, Candida albicans, Listeria monocytogenes and Pseudomonas syringae. PLE showed pronounced antimicrobial effects at concentrations at or above 50 ${\mu}g$/mL. The activities were stable at $100^{\circ}C$ and over the pH range of 3-11. PLE may serve as a natural antimicrobial agent in food preservation. It is suggested that hydrophillic components in the extract synergistically perturb microbial membrane functions.

한국산 작약(Paeonia lactiflora Pall.) 뿌리를 사용하여 작약추출물(PLE)을 조제 후, 변패미생물에 대한 작약추출물의 항균력을 측정하였다. Paper disk 확산법에 의한 농도별 항균력 검사에서는 작약추출물이 농도에 비례하는 항균력을 나타내었다. 생육저해곡선의 측정에서는 50 ${\mu}g$/mL이상에서 미생물의 생육이 완전히 억제되는 것을 확인하였다. 열($100^{\circ}C$에서 45분처리) 및 pH(3~11)의 넓은 범위에도 항균력을 보여, 열 및 pH에 대한 작약추출물에 포함된 항균력의 우수한 안정성을 확인할 수 있었다. 전자현미경(SAM, TEM)에 의한 미생물생태변화의 관찰에서도 작약추출물의 항균물질이 세포벽 또는 세포막의 삼투기능을 상실시켜 미생물의 생리가 중단되고 억제되는 것을 확인하였다. 그리고 ${\beta}$-galactosidase의 효소활성측정결과 작약추출물은 미생물의 세포막 기능파괴를 심하게 초래하는 것으로 예상할 수 있었다.
