Natural hydroxytyrosol is present in olive leaves at a very low content of only 0.01-0.8%, and is mostly present in the form of esterified compounds (oleuropein) at various parts of olive. At present, HT is mainly separated from olive fruits, leaves, and residues and waste water generated in the process of preparing olive oil or table olive fruits, wherein oleuropein, ligustrin, verbascoside and other glycosides, flavonoid glycosides and polyphenols in the waste water are complex in components and low in separation efficiency. Chemical synthesis of HT has been reported, under the temperature of minus 25 ℃, under the conditions that Lucia, napolitano and the like are adopted, tyrosol is subjected to IBX oxidation and sodium thiosulfate reduction to obtain HT, and the yield is only 30%; 3, 4-dihydroxy phenylacetic acid is used as a raw material, lithium aluminum hydride, TMSCHNH/sodium borohydride and tetra-n-butylboroalkylated amine/methyl iodide are used as reducing agents, the yield is lower than 50%, the raw material and the catalyst are expensive in cost, the reaction conditions are harsh, and industrial preparation cannot be achieved.

Oleuropein (OE) is a cycloolefine ether polyphenol compound, is easily influenced by factors such as air, sunlight, acid, alkali, an oxidant, transition metal ions, long-time high temperature and the like, is subjected to reactions such as oxidation, condensation, chelation and the like and is damaged, and is easily degraded into HT and elemi acid under the action of acid, alkali and enzyme.

When the oleuropein and the hydroxytyrosol are conventionally extracted from fresh olive leaves, the oleuropein and the hydroxytyrosol are dried and crushed and then are introduced into an extraction tank, wherein continuous operation cannot be realized during loading and unloading, so that the extraction efficiency of the oleuropein and the hydroxytyrosol is influenced; and the temperature of the leaching tank needs to be maintained undeterminably, thereby increasing energy consumption.
