Abstract: Three new clerodane-type diterpene glycosides, (5R,6S,8R,9S,10R)-6-O-[β-D-glucopyranosyl-(1→4)-α-L-rhamnopyranosyl] cleroda-3,13(16),14-diene (1), (5R,6S,8R,9S,10R,13S)-6-O-[β-D-glucopyranosyl-(1→ 4)-α-L-rhamnopyranosyl]-2-oxoneocleroda-3,13-dien-15-ol (2), (5R,6S,8R,9S,10R)-6-O-[β-D-glucopyranosyl-(1→ 4)-α-L-rhamnopyranosyl]-(13E)-2-oxoneocleroda-3,14-dien-13-ol (3), together with two known compounds 4 and 5 were isolated from Dicranopteris pedata. The structures of these compounds were elucidated by detailed spectroscopic analysis, and the absolute configuration of compound 2 was determined by ECD calculations. In addition, compound 1 exhibited weak inhibitory activities against SMMC-7721, MCF-7 and SW480.
