摘要:
从蕨类毛蕨(Elaphoglossum piloselloides)的阿根廷收集物的二乙醚提取物中分离出了两个新的双环螺葡糖醇。通过分析其光谱数据(1 H NMR,HRMS,IR)和化学衍生化来建立结构。两种化合物均对血吸虫病媒介蜗牛Biomphalaria peregrina表现出急性杀灭软体动物的活性。

Two new bicyclic phloroglucinols were isolated from the diethyl ether extract of an Argentine collection of the fern Elaphoglossum piloselloides. Structures were established by analysis of their spectroscopic data (1H NMR, HRMS, IR) and chemical derivatization. Both compounds show an acute molluscicidal activity against the schistosomiasis vector snail Biomphalaria peregrina.
