Leuco-fisetinidin
Leuco-fisetinidin is a flavan-3,4-diol (leucoanthocyanidin), a type of natural phenolic substance. It is the monomer of condensed tannins called profisetinidins. Those tannins can be extracted from the heartwood of Acacia mearnsii [1] or from the heartwoods of Schinopsis balansae, Schinopsis quebrachocolorado and from commercial quebracho extract.[2]
