Method : using the method of alkaline extraction-acid precipitation crude extraction of rutin from Sophora to get the rude product .
Using acid hydrolysis method :We used acid hydrolysis of quercetin of rutin and thin-layer chromatography (TLC) for identification.
Conclusion: There were quercetin ,glucose and rhamnose after hydrolysis of rutin .
