Abstract
Scrodentosides A-E (1-5), five new acylated iridoid glycosides, together with 19 known ones, were isolated from the whole plant of Scrophularia dentata Royle ex Benth. The structures of these isolated glycosides were elucidated by spectroscopic methods. Bioassay showed that compounds 7 and 11 had significant inhibitory effect against NF-κB activation with IC50 value of 43.7 μM and 1.02 μM respectively.
