Leucoantocianina (flavan-3,4-dioles) son compuestos químicos incoloros relacionados con antocianidinas y antocianinas. Leucoantocianinas se pueden encontrar en Anadenanthera peregrina y en varias especies de Nepenthes incluyendo N. burbidgeae, N. muluensis, N. rajah, N. tentaculata, y N. × alisaputrana.[1]

Tales compuestos incluyen:

Leucoantocianidinas han demostrado ser intermedios en la biosíntesis de antocianidina en las flores de Matthiola incana.[3]


Metabolism

Leucoanthocyanidin dioxygenase utiliza flavan-3 ,4-dioles para producir 3-hydroxyanthocyanidins.[4]​ El gen que codifica la enzima (PpLDOX) se ha identificado en el melocotón[5]​ y ha sido estudiado en Vitis vinifera.[6]
