Objective: To establish a determination method for the extraction of total flavonoids in Morus alba. Method: The sanggenon C was used as the authentic standard. The content of total flavonids was determined by the HCl-Mg reaction colorimetry
measurement wavelength was set at 481 nm. Result: The sanggenon C calibration curve showed a good linear relationship in the ranger of 146.8-734.0 mg·L-1 (n=5
r=0.999 8) and the average recovery was 96.74%
RSD 2.60% (n=6). Conclusion: The method established was reliable and accurate. It can be used to determine the content of total flavonoid in M. alba.
