This invention discloses a method for preparing olea leaf extract rich in high-purity oleuropein. The method comprises: extracting olea leaves with polar solvent, centrifuging to obtain the supernatant and the precipitate, performing composite membrane separation to obtain concentrated solution passing through the nanofiltration membrane, adsorbing with an adsorption medium, eluting the adsorption medium to obtain the eluate, vacuum-concentrating, and freeze-drying or spray-drying in vacuum to obtain olea leaf extract rich in high-purity oleuropein (more than 50%). The method adopts composite membrane separation and medium adsorption techniques to replace traditional solvent extraction technique, thus can increase oleuropein purity, save energy and eliminate pollution. The polar solvent can effectively extract oleuropein, and the nonpolar solvent can effectively remove liposoluble substances, thus is advantageous for increasing oleuropein yield and purity.

The invention discloses a method for preparing high-purity hydroxytyrosol by using high-speed counter-current chromatography and high performance liquid chromatography in a combined manner. The method comprises the following steps of performing enzymolysis on an olive leaf extract; extracting with ethyl acetate and concentrating into hydroxytyrosol ointment of which hydroxytyrosol content is 5%-20%; mixing solvents such as petroleum ether, ethyl acetate, methanol and water proportionally; using the mixture as a high-speed counter-current solvent system under the condition that an upper phase is a fixed phase while a lower phase is a mobile phase; dissolving the hydroxytyrosol ointment in the lower phase to obtain a test article; fully filling multilayered coil separating columns of a high-speed counter-current chromatographic instrument in the fixed phase; injecting the mobile phase at revolving speed of 500-1800 r/min and at flowing speed of 1-5mL/min; and detecting by using an ultraviolet detector of which the wave length is 210-280 nanometers. Normal phase centrifugal rotation is implemented in a whole centrifugal process for 30-300 minutes.
