Objective:
To investigate the chemical constituents in Flos Sophorae Carbonisatus.
Method:
Silica gel column chromatography was used to separate and purify the chemical constituents. The structures were elucidated by spectral analysis.
Result:
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).
Conclusion:
4 is a new compound, and 1,2,3,5 were first reported from Flos Sophorae Carbonisatus.
