Chemical Information
FooDB NamePetunidin
DescriptionIsolated from bilberries (Vaccinium myrtillus), giant granadilla (Passiflora quadrangularis), Amonum subulatum (Nepal cardamon) and other plantsand is also found in red table wine and red wine vinegar. Glycosides also widely distributed Petunidin is an anthocyanin.; Anthocyanins are water soluble pigments belonging to the flavonoids compound family involved in nature in a wide range of functions such as flowers, fruits, and seeds pigmentation to attract pollinators, to disperse seeds, to protect against UV light damage, and in plant defense to protect against pathogen attack. Because anthocyanins impart much of the color and flavor of fruits and vegetables, they are usually components of the human diet and are not only considered exclusively as food products but also as therapeutic agents; in fact, anthocyanins have been suggested to protect against oxidative stress, coronary heart diseases, certain cancers, and other age-related diseases. At least part of these presumed health-promoting features can be attributed to the antioxidant properties of these compounds whose chemical structure appears ideal for free radical scavenging.
