Olive Leaf Extract is extracted from the leaves of Olea Europaea, commonly called olive tree. The main components of olive leaf extract are iridoid bitter substances, and the most active ones are oleuropein and hydroxytyrosol. Olive leaf extract has double the antioxidant capacity of green tea and four times the content of Vitamin C. It is widely used as olive leaf extract in health products and cosmetics.Specifications: Oleuropein 10%-80%; Hydroxytyrosol 3%-50%; Oleanolic acid 60% 70% 98% .

Hydroxytyrosol is a natural polyphenolic compound with strong antioxidant activity, mainly in the form of esters in the fruits and leaves of olives.

Hydroxytyrosol is an active ingredient in olives and acts as a highly active antioxidant in the human body. Antioxidants are bioactive molecules found in many plants, but their activity varies. Hydroxytyrosol is regarded as one of the most powerful antioxidants and the market demand is increasing. Its oxygen radical absorption capacity is about 4,500,000μmolTE/100g: 10 times that of green tea, and more than twice that of CoQ10 and quercetin
