Abstract: Seven types of macroporous resin were used to compare their performances in absorbing and desorbing thephenylethanoid glycosides from Cistanche tubulosa (Schenk) R.Wight. Resin AB-8 was the better one for the phenylethanoidglycosides with an adsorption capacity of 57.12mg/g and an desorption ratio of 90.32%. AB-8 absorbent capacity was also studied.Experiment results showed that AB-8 possessed the highest absorption capacity under the condition of pH 3.43, concentrationof sample 3.6~6.0mg/ml and flowing rate of 1.5BV/h.Using 40% ethanol as eluent, desorption ratio of the phenylethanoidglycosides reached 94.15% and elution peak was approximatively symmetric.
