Abstract
Six furano-ent-labdanes, 19-acetoxy-15,16-epoxy-8(17),13(16),14-ent-labdatr ien-20-al, 15,16-epoxy-12-oxo-8(17),13(16),14-ent-labdatrien-20,19-olide, 1 2(S)-hydroxy-15,16-epoxy-8(17),13(16),14-ent-labdatrien-20,19-olide, 10 alp ha ,19-dihydroxy-15,16-epoxy-8(17), 13(16),14-nor-ent-labdatriene, 19,20-di hydroxy-15,16-epoxy-8(17),13(16),14-ent-labdatriene, 15,16-epoxy-12-oxo-8(1 7),13(16),14-ent-labdatrien-19,20-olide, were isolated, together with the k nown potamogetonin, from the aquatic plant Potamogeton natans. Their struct ures were determined on the basis of their chemical and spectral data. The compounds showed in vitro phytotoxicity against Raphidocelis subcapitata, a microalga used in aquatic tests.
