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

Natural occurrences[edit]

Presence in flowers[edit]

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.

Presence in food[edit]

Pelargonidin can be found in berries such as ripe raspberries and strawberries, as well as blueberries, blackberries, cranberries but also in saskatoon berries[2] and chokeberries. It is also found in plums and pomegranates.

It is present in large amounts in kidney beans.[3]

Glycosides[edit]

Pelargonidin-3-O-glucoside (callistephin) can be found in strawberries.[4]

Acylated pelargonidin glycosides can be found in red-purple flowers of Ipomoea purpurea.[5]
