In order to establish the method for mensurating total flavonoids content in Camellia chrysantha (Hu) Tuyama, UV spectrophotometry method is employed. As a result, in the range of 0.008 64-0.069 12 mg/ml, the linear relationship is good(r=0.999 9), the average recovery rate is 100.4% and RSD is 0.018 0%. Therefore, the method is simple and reliable and thus can be used to control the quality of C. chrysantha.
