A Furanoid Labdane Diterpene from Potamogeton nodosus

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 act...

Zusammenfassung:	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.
