摘要：

Separation of a lipophilic extract of the bryozoan, Dakaira subovoidea, a common fouling organism of underwater structures, guided by inhibition of lipid peroxide formation in rat liver microsomes, gave 5,7-dihydroxy-1-hydroxymethyl-6-oxo-6H-anthra[1,9-bc]thiophene (1a) and its 1-methoxycarbonyl derivative (1c), together with the known 1,8-dihydroxyanthraquinone (2). The structures were determined by spectral and crystallographic analyses.
