Abstract: Using five-factor and four-level orthogonal test,the characteristics of HPD300 macroporous resin for purifying flavonoids of Fortunella margarita were studied. The results showed the HPD300 macroporous resin has better purifying ability for the flavonoids. On the conditions of crude flavonoids solution pH 4.5,adsorption time 4 h,ratio of 80 % ethanol(desorption solution) volume to the resin weight 25:1 and desorption time 2 h,the recovery rate of the flavonoids is 75.6 %,and the purity is 38.2%.

Key words: flavonoids from Fortunella margarita peel, HPD300 macroporous resin, purification
