8 '-hydroxyzearalanone and 2 '-hydroxyzearalanol: Resorcyclic acid lactone derivatives from the marine-derived fungus Pencillium sp.

Two new 14-membered resorcyclic acid lactone derivatives, 8'-hydroxyzearalanone (1) and 2'-hydroxyzearalanol (2), and four known zearalanone derivatives (3-6) were isolated from the marine-derived fungus Penicillium sp. The structures of compounds 1-6 were elucidated by spectroscopic methods.
