Popis: Three new triterpenoid glycosides, 3 β -hydroxy-28-norolean-12-ene-16-one 3- O -β- d -glucopyranoside ( 1 ), 3 β ,17 β -dihydroxy-28-norolean-12-ene-16-one 3- O -β- d -glucopyranoside ( 2 ) and 3 β -hydroxy-olean-12-ene-16,28-lactone 3- O -β- d -glucopyranoside ( 3 ) together with eclalbasaponin II ( 4 ) were isolated from Acanthopanax senticosus (Rupr. & Maxim.) Harms. Their structures were elucidated on the basis of spectroscopic and physico-chemical analyses. Inhibition of NF- κ B of these isolates was measured in HepG2 cells using a luciferase reporter system. Among the isolates, compounds 1 , 2 and 4 inhibited NF- κ B activation stimulated by TNF-α in a dose-dependent manner, with IC 50 values ranging from 8.3 ± 0.7 to 13.5 ± 1.0 μM.
