Abstract:
Three new clerodane-type diterpene glycosides, (5 R ,6 S ,8 R ,9 S ,10 R )-6- O -[ β - d -glucopyranosyl-(1 → 4)- α - l -rhamnopyranosyl]cleroda-3,13(16),14-diene ( 1 ), (5 R ,6 S ,8 R ,9 S ,10 R ,13 S )-6- O -[ β- d -glucopyranosyl-(1 → 4)- α - l -rhamnopyranosyl]-2-ox-oneocleroda-3,13-dien-15-ol ( 2 ), (5 R ,6 S ,8 R ,9 S ,10 R )-6- O -[ β - d -glucopyranosyl-(1 → 4)- α - l -rhamnopyranosyl]-(13 E )-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. Graphic Abstract
