Trollius chinensis Bunge, Stems more than 20 cm tall, to 80 cm at fruiting, simple. Basal leaves 1--4; petiole 12--30 cm, base narrowly sheathed; leaf blade not green when dried, pentagonal, 3.8--6.8 × 6.8--12.5 cm, base cordate, 3-sect; central segment rhombic, 3-fid to or beyond middle, margin densely unequally dentate; lateral segments obliquely flabellate, 2-fid nearly to base. Three new flavone C-glycosides with the substitution of the unusual acyl, 2'-O-veratroylisoswertisin (1), 3'-O-2-methylbutyrylisoswertiajaponin (2), and 3'-O-2-methylbutyrylvitexin (3), together with the known compounds of 2'-O-2-methylbutyrylisoswertisin (4), 3'-O-2-methylbutyrylisoswertisin (5), and trollisin I (6) were isolated from the antibacterial fraction of the aqueous extract of the flowers of Trollius chinensis.
