Applicazioni

Neoxanthin has been used as a reference standard to determine the phenolic content and antioxidant activity of Phaeodactylum tricornutum extracts by high-performance liquid chromatography (HPLC).

Azioni biochim/fisiol

Neoxanthin is an allenic xanthophyll and one of the major carotenoids found in plants such as spinach and barley leaves. A trace amount of this pigment is also found in olive oil. Neoxanthin exists as two geometric isomers such as trans-neoxanthin and 9′-cis-neoxanthin. It acts as a precursor of abscisic acid. It plays a role in photoprotection by providing general antioxidant activity. Neoxanthin exhibits apoptotic and anti-proliferative effects.
