Common NamePetunidin
DescriptionPetunidin, also known as petunidin chloride (CAS: 1429-30-7), belongs to the class of organic compounds known as 3'-O-methylated flavonoids. These are flavonoids with methoxy groups attached to the C3' atom of the flavonoid backbone. Petunidin is an extremely weak basic (essentially neutral) compound (based on its pKa). Outside of the human body, petunidin has been detected, but not quantified in, several different foods, such as saffrons, french plantains, highbush blueberries, bilberries, and fruits. This could make petunidin a potential biomarker for the consumption of these foods. Petunidin is an anthocyanin. Anthocyanins are water-soluble pigments belonging to the flavonoids compound family that are widespread in nature and involved in numerous functions such as flower, fruit, and seed pigmentation to attract pollinators, seed dispersion, UV light protection, and plant defence against pathogen attack. Because anthocyanins impart much of the colour and flavour 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 (PMID: 16277406 ). BioTransformer predicts that petunidin is a product of peonidin metabolism via a hydroxylation-of-benzene-ortho-to-edg reaction catalyzed by the CYP1A2, CYP2C9, and CYP3A4 enzymes (PMID: 30612223 ).
