A new combined technology: Macroporous adsorption resin and high speed counter current chromatography for hydroxytyrosol separation from olive leaf enzymatic hydrolysate

•Separation and purification technology of HT from EEEH was investigated withMAR and HSCCC).•Adsorption properties of H-103 macroporous resin was best for purifying HT from EEEH under the same other conditions.•HT purity of EEEH was increased from 10.23 % to 40.78 % with the optimal MAR technology.•...
