초록
달맞이꽃 (Oenothera odorata Jacquin)의 뿌리로 부터 천연항균성분을 분리하고 그 특성을 조사하였다. 주성분은 chloroform 추출분획중에 존재하는 TLC의 Rf값 0.39[전개용매계, toluene : ethyl acetate : formic acid (7 : 4 : 0.8)]의 것이였으며 NMR 분석결과 방향족고리를 포함하는 steroid계통의 화합물로서 장파장의 자외선(365nm)을 흡수하며, Streptococcus속 균주에 대한 항균활성(MIC: 50)이 Staphylococcus 및 Escherichia속 균주에 대한 활성(MIC: 100~1600) 보다 월등히 높았다.
An antibacterial component was isolated from the roots of evening primrose(Oenothera odorata Jacquin). The component was purified by repeated preparative TLC of the chloroform-extract with solvent system of toluene(7):ethyl acetate(4):formic acid(O.8). NMR spectrum indicated that it is a steroid compound containing radical(-C=C-C=0) and aromatic structures. Its antibacterial activity against strains of the genus Streptococcus was relatively high, the MIC value was 50 acccording to the Hoechst Manual-345, as compared with the other genera such as Staphylococcus and Escherichia.
