    Journal: J Nat Prod; 1998 Jan; 61(1):156-7. PubMed ID: 9461667.
    Abstract:
    A new furanoid diterpene, 15,16-epoxy-12-oxo-8(17), 13(16), 14-labdatrien-20,19-olide (1) was isolated from an ethanolic extract of Potamogeton nodosus. Its structure was elucidated by the usual spectroscopic methods, including 2D NMR techniques. Compound 1 was found to exhibit moderate inhibitory activity against a number of both Gram-positive and Gram-negative bacteria.
