Hydroxytyrosol, as an anti-inflammatory, antibacterial and anticancer ingredient, has been widely used in medicine, cosmetics, daily chemicals and other fields. Hydroxytyrosol, as an important pharmaceutical and chemical raw material, can be prepared in a variety of ways through biological, chemical or physical methods.
Hydroxytyrosol can be extracted from olive oil residue, catalyzed and esterified by enzymes or acids. Hydroxytyrosol can also be obtained by reducing 3, 4-dihydroxyphenylacetic acid as raw material. Tyrosol or phenylethanol can be converted into hydroxytyrosol through biocatalysis or chemical treatment as raw materials, but this method is limited by raw materials and reactions, and is currently only used in laboratories. In addition, hydroxytyrosol can also be obtained by the reaction of catechol and glyoxylic acid.
There are many ways to prepare hydroxytyrosol, but in the face of mass production, the production process should meet the requirements of green environmental protection, economic safety and other requirements, so as to achieve long-term production and development.
