Three novel fatty acid derivatives (1-3), containing one or two butenolide
moieties, were isolated from the Caribbean gorgonian Pterogorgia anceps and
chemically characterized by spectroscopic methods and comparison with know
n compounds. The new molecules were structurally related to ancepsenolide (
4), a typical metabolite from Pterogorgia species, which was not detected i
n this collection of P, anceps.
