초록

Drechslera siccans의 배양 추출물로부터 이탈리안 라이그라스 (Lolium multiflorum Lam.) 뿌리의 생육저해 활성을 나타내는 물질을 분리정제한 다음에 2차원 NMR을 포함한 각종 기기분석을 이용하여 구조를 결정하였다. Siccanol(1)이라고 명명한 이 화합물의 분자식은 $C_{25}H_{38}_{4}$이었으며 100ppm에서 숙주 식물중의 하나인 이탈리안 라이그라스에 대하여 100%의 저해 활성을 나타내었다.

A bicyclic sesterterpene from Drechslera siccans was purified and structurally characterized. During the isolation procedure, the toxic component was monitored by the assay using Italian ryegrass (Lolium multiflorum Lam.), one of the host plants of the pathogen. Siccanol (1) named arbitrarily was shown to have a molecular formula of $C_{25}H_{38}_{4}$. Siccanol completely inhibited the root growth of the Italian regrass seedlings at a level of 100 ppm.
