  摘要：

  Five new compounds, 16,23,29-trihydroxy-3-oxo-olean-12-en-28-oic acid (1), 4,23,29-trihydroxy-3,4-seco-olean-12-en-3-oate-28-oic acid (2), 3 beta,6 beta,23-trihydroxyolean-12-en-28-oic acid 28-O-beta-D-glucopyranoside (3), 3-O-[2,3-di-O-acetyl-alpha-L-arabinopyranosyl]hederagenin 28-O-alpha-L-rhamnopyranosyl-(1 -> 4)-beta-D-glucopyranosyl-(1 -> 6)-beta-D-glucopyranoside (4), and 3-O-[3,4-di-O-acetyl-alpha-L-arabinopyranosyl]hederagenin 28-O-alpha-L-rhamnopyranosyl-(1 -> 4)-beta-D-glucopyranosyl-(1 -> 6)-beta-D-glucopyranoside (5), as well as 10 known compounds (6-15), were isolated from the stem bark of Kalopanax pictus. Compounds 1-5 and 7-14 inhibited TNF alpha-induced NF-kappa B transcriptional activity in HepG2 cells in a dose-dependent manner, with IC(50) values ranging from 0.6 to 16.4 mu M. Furthermore, the transcriptional inhibitory function of these compounds was confirmed on the basis of decreases in COX-2 and iNOS gene expression in HepG2 cells. The structure activity relationship of the compounds with respect to anti-inflammatory activity is also discussed.
