Abstract
Ethanol extract of barks, roots, stems, leaves and seeds of 49 species of plants were examined their growth inhibition by disk method on Listeria monocytogenes ATCC 19111, ATCC 19112, ATCC 19113, ATCC 19114 and ATCC 15313. The extracts exhibited comparatively strong growth inhibition were compared their activity with broth culture containing different concentration of the extracts. L. monocytogenes ATCC 19111 was inhibited by Siegesbeckia pubescens Makino and Morus alba Linne (Ma) extracts. L. monocytogenes ATCC 19112 and ATCC 19114 were inhibited by Ma extract. ATCC 19113 was inhibited by Sophora flavescens AITON and Ma extract. ATCC 15313 was inhibited by Foeniculum vulgare Gaertner, Prunella vulgaris Var lilacina Nakai and Ma extract. Ma extract showed comparatively good inhibition effect for 5 strains of L. monoytogenes. 500 ppm of Ma extract almost inhibited the growth of all L. monocytogenes tested.
식용 가능성이 있는 식물 49종의 열매, 줄기, 잎, 껍질 혹은 뿌리를 75% ethanol을 용매로 추출물을 얻고 이를 Listeria monocytogenes ATCC 19111, L. monocytogenes ATCC 19112, L. monocytogenes ATCC 19113, L. monocytogenes ATCC 19114 및 L. monocytogenes ATCC 15313을 대상으로 증식저해 정도를 disk method로 검색하고 효과가 있는 것은 액체 배지에 농도별로 첨가, 그 효과를 비교하였다. L. monocytogenes ATCC 19111에 비교적 높을 항균성을 보인 식물의 ethanol 추출물은 털진득찰, 뽕나무이고 L. monocytogenes ATCC 19112와 ATCC 19114에는 뽕나무, ATCC 19113에는 고삼, 뽕나무, ATCC 15313에는 뽕나무, 꿀풀, 회향 등 이었다 이들 식물 추출물중 광범위하게 항균성을 나타내는 뽕나무껍질 추출물은 실험한 L. monocytogenes 5종 모두에 대하여 500ppm 첨가 수준에서 대부분 완전 증식억제 현상을 보였다.
