Hi :

They say it is from the olive ****tree****. Do we know for sure it

is from the olives? Or might some other part of the plant be the

source?

The authors are contending that this compound is well-represented in the olives themselves, and cite the following piece of literature in support of that claim:

"Three simple phenols (tyrosol, hydroxytyrosol, and vanillic acid), a secoiridoid derivative (deacetoxy oleuropein aglycon), and two lignans (pinoresinol and acetoxypinoresinol) were detected as the main compounds in extra virgin olive oils by high-performance liquid chromatography (HPLC) and capillary zone electrophoresis (CZE)."

Apparently, the compound is an isolable component of the olive bitter fraction, a determination first reported in the following citation:
