Abstract

Extracts of common purslane(Portulaca oleracea L.) showed to possess some antifungal substances which inhibited the mycelial growth of the phytopathogenic fungi tested;Valsa mali, Alternaria kikuchiana and Pyricularia oryzae. These antifungal substances were found to be soluble in methanol and were regarded as kinds of lipid. In order to isolate the antifungal substances, the extracts of common purslane were concentrated by evaporation under reduced pressure and extracted with methanol The methanol solution was subjected to silica gel-florisil column and divided into lipid and non-lipid fractions. Lipid fractions only showed antifungal activity against the fungi tested. The effective substances contained in the extracts of common purslane inhibited not only the mycelial growth but also the spore germination of the fungi.

쇠비름즙액(汁液)(원액(原液))은 사과 부란병균(病菌)(Valsa mali), 배 검은무늬병균(病菌)(Alternaria kikuchiana), 벼 도열병균(病菌)(Pyricularia oryzae)등 몇가지 식물병원균(植物病原菌)에 대한 항균작용(抗菌作用)을 지니고 있다. 이와 같은 항균작용(抗菌作用)을 나타내는 물질(物質)은 메타놀에 잘 용해(溶解)되며 지질(脂質)에 속하는 물질(物質)로 추정(推定)된다. 그리고 쇠비름즙액(汁液)에 함유(含有)되어 있는 항균물질(抗菌物質)은 균채신장억제(菌采伸長抑制) 뿐만 아니라 포자발아억제(胞子發芽抑制) 효과(效果)를 보여주고 있다.
