Two new compounds, 2″-O-feruloylisoswertiajaponin (1) and (2E)-2-methyl-1-O-vaniloyl-4-β-d-glucopyranoside-2-butene (2), along with one indole alkaloid and five known flavonoids, were isolated from the flowers of Trollius chinensis Bunge. Their structures were elucidated on the basis of spectroscopic evidence (UV, IR, HR-ESI–MS, NMR).
