  Fom the fresh leaflets of a fern, Gleichenia japonica, four new labdane-type diterpenoid glycosides, 18-O-α-L-rhamnopyranosyl-(1→2)-β-D-glucopyranosyl-13-epitorreferol (1), 3-O-α-L-rhamnopyranosyl-(1→2)-β-D-glucopyranosyl-3β-hydroxymanool (2), 3-O-α-L-rhamnopyranosyl-(1→2)-β-D-glucopyranosyl-3β-hydroxy-13-epimanool (3), and 3-O-α-L-rhamnopyranosyl-(1→2)-β-D-glucopyranosyl-(13E)-labda-8(17), 13-diene-3β,15-diol (4), were isolated together with two known compounds, (6S, 13S)-6-O-α-L-rhamnopyranosyl-(1→2)-β-D-glucopyranosyl-6,13-dihydroxycleroda-3,14-diene (5) and 3-O-β-D-glucopyranosyl-13-O-α-L-rhamnopyranosyl-3β-hydroxymanool (6), and their structures were determined.
