Leucoanthocyanidin (flavan-3,4-diols) are colorless chemical compounds related to anthocyanidins and anthocyanins. Leucoanthocyanins can be found in Anadenanthera peregrina and in several species of Nepenthes including N. burbidgeae, N. muluensis, N. rajah, N. tentaculata, and N. × alisaputrana.

Such compounds include:

Leucoanthocyanidins have been demonstrated to be intermediates in anthocyanidin biosynthesis in flowers of Matthiola incana.

Bate-smith recommended in 1954 the use of the Forestal solvent for the isolation of leuco-anthocyanins.
