| Abstract: | Total flavonoids were extracted from Bergenia emeiensis leaf and rhizome,and the contents of flavonoids were detected by spectrophotometry.The results showed that the content of total flavanoids in B.emeiensis leaves was 9.246mg/g with the recovery rate of 98.33% and RSD of 1.17%,and the content of total flavanoids in B.emeiensis rhizome was 1.812mg/g with the recovery rate of 95.79 % and RSD of 1.10%. |
