Pure Olive Leaf Extract Oleuropein for Cosmetic Oil Introduction

Hydroxytyrosol is an active ingredient in olives and acts as a highly active antioxidant in the human body. Antioxidants This bioactive molecule is found in many plants but has different activities. Hydroxytyrosol is considered one of the most powerful antioxidants, and market demand is increasing. Its oxygen radical absorption capacity is about 4,500,000 μmol TE/100 g: 10 times that of green tea, and more than twice that of CoQ10 and quercetin. It can effectively protect the oxidative damage and mitochondrial dysfunction of retinal pigment epithelial cells caused by acrolein, a toxic component of cigarettes. The main mechanism is that hydroxytyrosol can induce a two-phase enzyme system with detoxification in cells. These results suggest that hydroxytyrosol may have protective effects on retinal pigment epithelial cell degeneration caused by smoking, such as macular degeneration. The results also support the diet rich in olive oil will be conducive to the treatment of diseases related to mitochondrial dysfunction such as diabetes and obesity.
