Abstract
Four lactone diterpenes and two related glucosides with a labdane skeleton have been isolated from the aquatic plant Potamogeton natans. The structures of three new compounds were determined as 19-acetoxy-20-oxo-8(17),13-ent-labdadien-15-->16 lactone, 8(17), 13-ent-labdadien-15-->16,19-->20 dilactone and 6'-acetyl-19-glucopyranosyloxy-8(17),13-ent-labdadien-15-->16 lactone, respectively, by means of spectral analysis. Antialgal assays showed inhibitory activity for some compounds.Entities:
