| Abstract: | The static adsorption and desorption characteristics of two macroporous resins（X-5 and AB-8） to purify flavonoids of Myrtle leaves were studied in the paper. The results showed that, X-5 displayed higher adsorption and desorption performance than the other resin. It was concluded that X-5 resin is the ideal macroporous resin for the purification of flavonoids in Myrtle leaves. The optimal adsorption condition was 25 ℃, 6 h, the flavones＇ solution with pH6.0, the adsorption rate was up to 66.07%. The optimal desorption condition was 30 ℃, 12 h, while 95 % ethanol was taken as the optimal desorption reagent. |
