초록
Bipolaris cynodontis의 배양 추출물로부터 이탈리안 라이그라스 뿌리의 생육저해 활성을 나타내는 물질을 분리 정제한 다음에 2차원 NMR을 포함한 각종 기기분석을 이용하여 구조를 결정하였다. 이 화합물의 분자식은
A phytotoxic compound was isolated from a culture of Bipolaris cynodontis, a fungus pathogenic to Bermuda grass. The structure was determined by spectroscopic analyses including 2D NMR experiments, to be sesquiterpene having a 9-carbon unit side chain. The compound inhibits the root growth of the seedlings of Italian ryegrass and rice plant, the host plant of the B. cynodontis, by about 100% at 100ppm, and it is suggested that this may play an important role in the expression of the disease symptom.
