The metabolites of the predacious fungus Dactylaria lutea ROUTIEN include the anthraquinone macrosporin (2) and three hydroxylated 1, 2, 3, 4-tetrahydro derivatives of this anthraquinone, altersolanol A (5), altersolanol B (4) and dactylariol (6). The structure and relative configuration of dactylariol are established from spectroscopic studies, and its absolute configuration is proposed as 1R, 2R, 3R by virtue of its co-occurrence with alter-solanol B. Dactylarin, suggested by other authors to have the structure (1), is shown to be identical with altersolanol B (4).
