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:

Leucocianidina
Leucodelfinidina
Leucofisetinidina
Leucomalvidina
Leucopelargonidina
Leucopeonidina
Leucorobinetinidina
Melacacidina
Teracacidina de Acacia obtusifolia y Acacia maidenii^[2]

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]
