| Abstract: | Objective] The aim was to establish the method for determining total flavonoids content in Camellia chrysantha(Hu)Tuyama.. Method] UV spectrophotometry was adopted to determine the content of total flavonoids. Result] The results showed that in the range of 0.008 64-0.069 12 mg/ml,linear relationship was good (r=0.999 9),the average recovery rate was 100.4%,RSD was 0.018 0. Conclusion]The method is simple and reliable,which could be used to control the quality of C. chrysantha. |
