Five new compounds, kalopanaxsaponin G (2) and kalopanaxins A (6), B (8), C (11) and D (13), were isolated from the bark of Kalopanax pictus together with nine known compounds, kalopanaxsaponins A (1) and B (5), pericarpsaponin PJ3 (3), hederasaponin B (4), syringin (7), protocatechuic acid (9), coniferin (10), liriodendrin (=dl-syringaresinol di-O-glucopyranoside) (12), glucosyringic acid (14) and chlorogenic acid (15). The structures of the new compounds were characterized as hederagenin 28-O-α-L-rhamnopyranosyl(1→4)-β-glucopyranosyl(1→6)-β-D-glucopyranoside (2), ferulyldehyde (=coniferylaldehyde) 4-O-β-D-glucopyranoside (6), coniferin 6'-O-(4-O-α-L-rhamnopyranosyl)-syringate (8), 2-methoxyhydroquinone 4-O-[6-O-(4-O-α-L-rhamnopyranosyl)-syringyl]-β-D-glucopyranoside (11) and coniferyl alcohol 4-O-β-D-apiofuranosyl(1→2)-β-D-glucopyranoside (=coniferin 2'-O-β-D-apiofuranoside) (13).
