Characteristics Of The Arisi Concentrated Glycerol Extract Of Olive Leaf Polyphenols


Arisi Olive leaf extract is produced using olive leaves that are picked from the trees and worked few hours after in a factory where several separation plants are available, including chromatography, fractional and molecular distillation ones.
The solvent used is glycerol a non toxic substance commonly present inside the human body, instead of the commonly used ethanol.

The Arisi Olive leaf extract contains a relatively high content of Hydroxytyrosol, but contains also the range of the phenolic compounds present in the olive leaves including the most polar ones, that normally are not extracted with the standard ethanol extractions. Many of them are still not known by science, but all of them have a synergetic role and are naturally present, not only the leaves, but also in all the olive tree including fruit and, in small quantity, in extra virgin olive oil.
