摘要
The aerial parts of Spergula fallax afforded four glycosides (1-4) based on two new triterpene aglycones (1a and 2a), along with the known hopane glycoside succulentoside A. Compound 1 was identified as belonging to the fernane class, unusual migrated hopane triterpenoids, mainly isolated from ferns and only rarely from higher plants. Compounds 2-4 were assigned as gammacerane glycosides, having as aglycone a hydroxylated derivative of tetrahymanol. The structures of the isolated compounds 1-4 and their aglycones 1a and 2a obtained by acid hydrolysis were elucidated by spectroscopic data interpretation. The growth inhibitory activity of the isolated compounds and their aglycones was evaluated against the HeLa and DLD-1 cancer cell lines.
