Four new flavonoid glucosides, 2″-O-(6‴-O-caffeoyl)-galactopyranosylvitexin (1), 2″-O-(6‴-O-veratroyl)-galactopyranosylvitexin (2), 2″-O-(6‴-O-feruloyl)-galactopyranosylorientin (3), 2″-O-(2‴-O-methylbutyryl)-glucopyranosylisoswertisin (4), along with three known compounds were isolated from the flowers of Trollius chinensis Bunge. Their structures were determined by extensive spectroscopic analyses.
