ABSTRACT
OBJECTIVE:
To study the conditions and parameters of the enrichment of oleuropein with macroporous resin.METHODS:
Aqueous extract of Olea europaea leaves prepared through microwave extraction was adsorbed directly with macroporous resin D-101 and the impurities such sugar were washed out by water then oleuropein was eluted by 70% ethanol. HPLC was used to determine the content of oleuropein.RESULTS:
The contents of oleuropein increased from 5% to 21.6% in the solid, with 88.6% of recovery rate.CONCLUSION:
Macroporous resin D-101 fits in purification of water-soluble oleuropein. The process is simple and convenient and can be used for industrial production.
