Abstract:
Studying the influence of temperature to the content of flavonoids in Flos Sophorae showed that the dried temperature make the significant changes the content of rutin and quercetin in Flos Sophorae. The rutin content increased when drying over a fire at 80oC-120oC, quercetin did not be changed much; at 140oC-180oC, the contents of rutin decreased slightly, quercetin increased slightly. At 200oC-220oC, the contents of rutin decreased clearly, quercetin increased clearly. These results can be applied for the standardization of Flos Sophorae using roasting methods for traditional medicines
