Abstract

Structurally unique new sesquiterpenoid quinones dactyloquinone A (1) and B (2), each possessing a dihydropyran moiety, were isolated from an Okinawan sponge Dactylospongia elegans, along with known sesquiterpenoid quinones. The structures of these compounds were determined by spectroscopic analysis.

摘要

从冲绳海绵优雅指海绵（Dactylospongia elegans）中分离出结构独特的新型倍半萜醌类化合物指醌A（1）和指醌B（2），它们各自含有一个二氢吡喃部分，同时还分离出了已知的倍半萜醌类化合物。通过光谱分析确定了这些化合物的结构。
