To investigate the chemical constituents in Flos Sophorae Carbonisatus. Silica gel column chromatography was used to separate and purify the chemical constituents. The structures were elucidated by spectral analysis. Six compounds were isolated from Flos Sophorae Carbionisatus, and their structures were elucidated as maltol (1), 3-hydroxypyridine (2), malto-3-O-[6'-O-(4"-hydroxy-tans-cinnamoyl)-beta-D-glucopyranoside (3), 3-O-[beta-D-galactopyranosyl-(1-->2)-beta-D-glucuronopyranosyl] sophoradiol ethyl ester (4), 3-O-[beta-D-galactopyranosyl-(1-->2)-beta-D-glucuronopyranosyl] sophoradiol methyl ester (5), rutin (6). 4 is a new compound, and 1,2,3,5 were first reported from Flos Sophorae Carbonisatus.
