Objective To determine the content of total flavonoids in Codonpsis thalictrifolia Wall. by UV-spectrometry.Methods Total flavonoids was extracted with 80% ethanol and rutin was used as reference substance. The content was detected at 365nm.Results The average recovery rate was 95.13%, RSD was 2.8% and the content of total flavonoids was 0.0875%.Conclusion This method is simple and reliable and can be used for determination of the content of total flavonoids.
