Abstract
Two new compounds, 5-carboxymethyl-2-propylchromone (1) and 1,6-dihydroxy-8-propylanthraquinone (2), together with a known anthraquinone, 3,8-dihydroxy-1-propylanthraquinone-2-carboxylic acid (3), were isolated from the mycelium of an actinomycete, Streptomyces sp. FX-58, which was separated from a marine plant collected in Qingdao. Their structures were determined based on spectroscopic methods, especially 2D NMR spectral analysis.
