性狀：羥基酪醇是橄欖葉中橄欖多酚的最主要成分，含量高達60%-80%，是天然抗氧化劑。為淺黃色油狀液體，是一種天然多酚類化合物，具有多種生物和藥理活性。羥基酪醇是橄欖中的一種活性成分，在人體內(nèi)起到高活性抗氧化劑的作用。抗氧化劑這種生物活性分子存在于很多植物中，但活性不盡相同。羥基酪醇被視為抗氧化劑之一，市場需求量日益高漲。

Introduction

Properties: Hydroxytyrosol is a phenylethanoid, a type of phenolic phytochemical with antioxidant properties in vitro. In nature, hydroxytyrosol is found in olive leaf and olive oil, in the form of its elenolic acid esteroleuropein and, especially after degradation, in its plain form. Hydroxytyrosol itself in pure form is a colorless, odorless liquid.

Functions: The olives, leaves and olive pulp contain large amounts of hydroxytyrosol (compared to olive oil), most of which can be recovered to produce hydroxytyrosol extracts. However, it was found that black olives, such as common canned variety, containing iron(II) gluconate contained little hydroxytyrosol, as iron salts are catalysts for its oxidation. Hydroxytyrosol is mentioned by the scientific committee of the European Food Safety Authority as one of several olive oil polyphenols under preliminary research for the potential to affect blood lipid levels.
