Abstract: In order to determine the optimum conditions and antioxidant activity of total alkaloids from leaves Mahonia
fortunei by macroporous resinsꎬ the best resins were selected by comparing the static adsorption and desorption effects of
six kinds of macroporous adsorption resins on total alkaloids. The optimum process conditions for the dynamic purification
of total alkaloids were investigatedꎬ and the anti ̄oxidation performance of total alkaloids before and after purification was
evaluated by DPPH method. The results were as follows: ( 1) AB ̄8 macroporous adsorption resins had the best
 ̄1
purification effects. The optimum process conditions were crude herbal dose of 50 mgmL ꎬ sample volume of 26 BVꎬ
 ̄1
sample flow rate of 2 BVh ꎬ eluted successively with 3 BV water and 4 BV 50% ethanol. Under these optimized
conditionsꎬ the content of total alkaloids was increased from 13.33% to 56.64%. (2) The total alkaloids had good
