| Oleuropein is a chemical compound found in olive leaves from the olive tree (and leaves of privet) together with other closely related compounds such as 10-hydroxyoleuropein, ligstroside, and 10-hydroxyligstroside. All these compounds are tyrosol esters of elenolic acid that are further hydroxylated and glycosylated. Oleuropein and its metabolite hydroxytyrosol have powerful antioxidant activity both in vivo and in vitro and give extra-virgin olive oil its bitter, pungent taste. Oleuropein preparations have been claimed to strengthen the immune system. | |
| Hydroxytyrosol, 3, 4-dihydroxyphenylethanol, 3-Hydroxytyrosol | |
| Chemical Name: | 4-(2-Hydroxyethyl)benzene-1,2-diol |
| CAS No.: | 10597-60-1 |
| Molecular Formula: | C8H10O3 |
| Mol. Wt.: | 154.16 |
| Hydroxytyrosol (3, 4-dihydroxyphenylethanol; DOPET) is a phytochemical with antioxidant properties. After gallic acid, hydroxytyrosol is believed to be one of the most powerful antioxidants. Its oxygen radical absorbance capacity(ORAC) is 40,000 umolTE/g, which is ten times higher than that of green tea, four times higher than that of VC, and two times higher than that of CoQ10. | |
| In nature, hydroxytyrosol is found in olive oil in the form of its elenolic acid ester oleuropein and, especially after degradation, in its plain form. Both compounds, along with oleocanthal, are responsible for the bitter taste of extra virgin olive oil. The olives, leaves, and olive pulp contain small amounts of hydroxytyrosol, most of which can be recovered to produce hydroxytyrosol extracts. | |
What is Oleuropein? |
|
| Oleuropein is the leaf of the olive leaf. While olive oil is well known for its flavor and health benefits, olive leaf has been used medicinally in various times and places. Natural olive leaf and olive leaf extract oleuropein is now marketed as an antiaging, immunostimulator, and antibiotic. | |
| Clinical evidence has proven the blood pressure lowering effects of carefully extracted olive leaf extract oleuropein. Bioassays support its antibacterial, antifungal, and anti-inflammatory effects at a laboratory level. Best quality oleuropein extract from Rongsheng biotechnology in China, A liquid extract made directly from fresh olive leaf recently gained international attention when olive leaf extract oleuropein was shown to have an antioxidant capacity almost double green tea extract and 400% higher than vitamin C. | |
