[Studies on chemical constituents in Flos Sophorae Carbonisatus].
OBJECTIVE
To investigate the chemical constituents in Flos Sophorae Carbonisatus.


METHODS
Silica gel column chromatography was used to separate and purify the chemical constituents. The structures were elucidated by spectral analysis.


RESULTS
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).


CONCLUSIONS
4 is a new compound, and 1,2,3,5 were first reported from Flos Sophorae Carbonisatus.
