Abstract
The invention relates to a method for purification of taxifolin. The process steps are as below: (1) crushing Douglas fir, adding ethanol solution, carrying out ultrasonic extraction, filtering and conducting vacuum concentration on the filtrate; (2) passing the concentrate through a macroporous resin adsorption column, washing by water to remove impurity, eluting the resin column by ethanol, and collecting alcohol eluent; and (3) concentrating the eluent to a state without alcohol taste, conducting ultrafiltration, nanofiltration condensation, and drying to obtain taxifolin. The method has the advantages of simple process, low cost, less pollution and good quality, and is an environment-friendly purification method.
