Objective:To determinate the contents of total flavonoids in the prepared medical herbs of Cy-peri Rhizoma from different areas.Method:The contents of total flavonoids were detected by UV while rutin was used as controller and measurement wavelength was 507 nm.Result:The results showed that rutin had a good Line-ar relationship in the concentrations between 3.0 mg.L-1 to 50.0 mg.L-1(r = 0.999 8).The contents of total flavonoids in most areas were 0.81%-1.75% except from Shanghai which was 0.42%.Conclusion:The contents of total flavonoids of the prepared medical herbs of Cyperi Rhizoma were higher and it may be used as one of quality index.
