['To study the conditions and parameters of the enrichment of oleuropein with macroporous resin.', '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.', 'The contents of oleuropein increased from 5% to 21.6% in the solid, with 88.6% of recovery rate.'] Does [ Study on the enrichment of oleuropein from Olea europaea leave with macroporous resin D-101 ]?
