After proper Friedel-Crafts post cross-linking reaction and animation under certain conditions, the new macroporous resins which have larger specific surface area and some alkalescent ion exchange groups have been prepared with polystyrene chloromethylated beads. Some physico-chemical properties and adsorption ability for total flavones of Chinese traditional medicines' decotum were tested. Detailed research on the adsorption of the resin to Radix Puerariae's total flavones have been done.
