Abstract
The methanolic extracts from the elm (Ulmus davidiana var japonica) root barks which have been known as an oriental medicine Eubackpie for the treatment of edema, ulcer and inflammation were examined for their bacteriocidal effects on mastitis pathogens of milk cows. The growth of the pathogenic bacteria such as Staphylococcus aureus and Streptococcus sp. No. 12 was markedly inhibited by the chloroform fraction among the extracts, and these antibacterial activities were also supported by MIC test. Water-soluble mucilage was obtained from the root barks with a yield of 36.8~40.2% by dry weight basis. This substance appeared to be a kind of polysaccharide with
젖소 유방염 병원균에 대한 느릅나무 뿌리껍질(유백피(楡白皮))의 항균활성을 검토하기 위하여 용매분획별로 시험한 결과 일반적으로 chloroform 분획이 가장 효과적이었고 butanol 및 물분획의 활성은 낮았다. 유방염균을 Fleish extract broth에서 액체 배양할 경우에 chloroform 분획을 첨가하면 생육이 억제되었으며 특히 Staphylococcus aureus 및 Streptococcus sp. No. 12는 초기생육이 현저하게 저해되는 경향을 나타내었다. Hoechst 제약의 표준방법에 의한 MIC 시험에서도 유사한 결과를 얻었다. 또한 건조한 느릅나무의 뿌리껍질 100 g을 물로 추출하여 겉보기 점도 77.5 cP, 최대흡수 파장 440nm의 황갈색 수용성 점질물 4.500ml를 회수할수 있었다. 이를 정제 건조한 무게는 32~35 g이었으며, 탄수화물 함량이
