大孔吸附树脂对金菊双花总黄酮的吸附研究

目的：筛选适合分离纯化金菊双花总黄酮的大孔吸附树脂，为其分离纯化提供实验依据。方法：选择14种大孔吸附树脂，比较其对总黄酮的吸附率、解吸附率及动力吸附曲线的影响。结果：大孔吸附树脂HPD100比较适合于金菊双花总黄酮的提纯，经该树脂吸附解吸，吸附量为69.30mg/g，解吸率可达87.1%。结论：大孔吸附树脂HPD100对金菊双花总黄酮具有较大的吸附量，易吸附、易解吸，性能优于其他树脂。

Study on the Absorption of Total Flavonoids in Lonicera japonica Thunb. and Chrysanthemum morifolium Tzvel. by Macroreticular Absorption Resins

Objective:To optimize the macroreticular absorption resins for purifying the flavonoids of Lonicera japonica Thunb.and Chrysanthemum morifolium Tzvel.,so as to provide an experimental basis for extraction and purification of the flavonoids.Methods:Comparing the absorption,desorption and absorption kinetics among fourteen kinds of macroreticular absorption resins.Results: Macroreticular absorption resin HPD100 was suited for purification of two flowers' flavonoids.Through its absorption and elution,the absorption capacity was 69.30 mg/g and elution ratio could reach 87.1%.Conclusion:Macroreticular absorption resin HPD100 possessed high absorption capacity,and was apt to absorb and elute,so its capability was obviously higher than any other resins.
