Hydroxytyrosol is a kind of polyphenols with various biological and pharmacological activities. It exists naturally in the leaves and fruits of olive branches, mainly in the form of lipids, and hydroxytyrosol has strong antioxidant activity.
Our bodies get hydroxytyrosol mainly from olive oil. It is the most antioxidant potential of all olive oils, but its levels are affected by the conditions of olive growth, processing and storage. Hydroxytyrosol has many derivatives, such as oleuropein, hydroxytyrosol acetate and its acetylated derivatives, which also have high biological activity.
Hydroxytyrosol can inhibit pro-inflammatory cytokines, effectively reduce the expression of cycidogenase and inducible nitric oxide synthase, prevent cell differentiation and apoptosis, and inhibit DNA oxidative stress.
Because of its special biological activity, hydroxytyrosol has a wide application prospect in medicine, health care products, cosmetics, food additives and other fields.
