Hydroxytyrosol Acetate

Hydroxytyrosol acetate [CAS # 69039-02-7, also known as 2-(3,4dihydroxyphenyl)-ethyl acetate or 4-(acetoxyethyl)-1,2-dihydroxybenzene]



Is a natural product first described in Spanish virgin olive oils (VOO) in 1999,
being its level about 7-fold higher than hydroxytyrosol in Hojiblanca VOO.
Since then, this compound has been identified not only in most of the olive
cultivars used in the production of VOO, but also increses its level during
fermentation of naturally black olives.
Pure hydroxytyrosol acetate

White solid vs the dense liquid of hydroxytyrosol.
• More stable than hydroxytyrosol to oxidation when
added
to VOO (measured by Ranciomat method).
• DPPH radical scavenger in oil better than that of
alpha-tocopherol or oleuropein.
• Better antioxidant in water than trans-resveratrol,
and a
35 % less efficient than hydroxytyrosol (ORAC
method).
• Liposoluble compound with a logP of 0.82 (close to
the
alpha-tocopherol value of 1.38 and far from the
anphiphilic
hydroxytyrosol with a value of 0.02).
• Non bitter compound, characteristics which make it
especially attractive for its possible use as a food
additive
in juices and dairy products.
Hydroxytyrosol in the
stomach

Usages of hydroxytyrosol acetate are the same as hydroxytyrosol
since it releases hydroxytyrosol in the stomach or intestine after
which this can be absorbed and pass to the blood stream.

It has been claimed for cosmetic applications, and for the prevention
and/or treatment of:
• Cerebral ischemic stroke.
• Cardiovascular, hepatic and renal diseases.
• Neurodegenerative diseases.
• Muscle damage after physical loads.
