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.
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[1] and chokeberries. It is also found in plums and pomegranates.
It is present in large amounts in kidney beans.[2]
Glycosides
Pelargonidin-3-O-glucoside (callistephin) can be found in strawberries.[3]
Acylated pelargonidin glycosides can be found in red-purple flowers of Ipomoea purpurea.[4]
