Ideain, the cyanidin 3-O- galactoside, is an anthocyanin, a type of plant pigment.
Ideain is the main anthocyanin in red-skinned [1] or red-fleshed (for example Weirouge) [2] apple varieties. It is also found in Chinese hawthorn fruits ( Crataegus spp.). [3] It is also the pigment in the copper beech (cultivar of Fagus sylvatica), that was identified in 1932. [4]
While it is only one in the many anthocyanins present in bilberries ( Vaccinium myrtillus) [5] and cranberries ( Vaccinium macrocarpon), [6] it is the main anthocyanin in lingonberries ( Vaccinium vitis-idaea). [7]
Quintinia serrata, the tawheowheo, a species of evergreen trees endemic to New Zealand, has different patterns of anthocyanins ( cyanidin 3-O-glucoside and cyanidin 3-O-galactoside) in its leaves to protect the shade-adapted chloroplasts from direct sun light. [8]
