摘要
A novel polyketide pigment （1） with the 4＇,10-coupled linkage between 1-naphthalenol and 1,4-anthraquinone, named rufoolivacin B together with the known analog rufoolivacin （2）, has been isolated from the fruiting bodies of the Chinese toadstool Cortinarius rufo-olivaceus （basidiomycetes）. Their structures were characterized by means of analysis of spectroscopic methods, including 2D-NMR experiments and HR-ESI-MS.
