Pelargonidin is an anthocyanidin, a type of plant pigment producing a characteristic orange color used in food and industrial dyes.[1]

Natural occurrences

Presence in flowers

Pelargonidin can be found in red geraniums (Geraniaceae). It is the predominant pigment causing the red coloration in the spathes of Philodendron (Araceae). The orange-coloured flowers of blue pimpernel (Anagallis monelli, Myrsinaceae) have a higher concentration of pelargonidin pigment. Red and Pink Roses (Rosa) obtain their color from this phytochemical. [2]

Presence in food

Pelargonidin can be found in berries such as ripe raspberries and strawberries, as well as blueberries, blackberries, cranberries but also in saskatoon berries[3] and chokeberries. It is also found in plums and pomegranates. Pelargonidin gives red radishes their color.[4]

It is present in large amounts in kidney beans.[5]

Glycosides

In many plant systems, Pelargonidin can be added to a glucose molecule to form Pelargonidin 3-glucoside (callistephin). This is done by the 3GT, anthocyanin 3-O-glucosyltransferase gene. [6]

Pelargonidin 3-glucoside.

However this glucosidation reduces its antioxidant activity,[7] and changes the wavelength of max light absorbance from 520 nm to 516 nm. [8]

Acylated pelargonidin glycosides can be found in red-purple flowers of Ipomoea purpurea.[9]
