[Chemical constituents in Flos Sophorae Carbonisatus].
OBJECTIVE
To investigate the chemical constituents of lipid-soluble and water-soluble extracts in Flos Sophorae Carbonisatus.


METHODS
The compounds were isolated by means of solvent extraction and column chromatography, and their structures were determined by spectral analysis.


RESULTS
Two compounds from petroleum ether extract and ten from n-BuOH extract were isolated and identified as sophoradiol (1), beta-sitosterol (2), 3 beta, 22 beta, 24-trihydroxy-olean-12-ene (soyasapogenol B) (3), daucosterol (4), kaikasaponin I (5), quercetin (6), isorhamnetin (7), 2-O-methyl-insitol (8), isorhamnetin-3-O-rutinoside (9), isoquercitrin (10), orobol-7-O-beta-D-glucoside (11), rutin (12), respectively.


CONCLUSIONS
Compound 3, 8-11 were isolated from Flos Sophorae Carbonisatus for the first time. The results could be basic foundation for further study on processing mechanism of Flos Sophorae Carbonisatus.
