Chemistry:Leucopelargonidin
Leucopelargonidin is a colorless chemical compound related to leucoanthocyanins. It can be found in Albizia lebbeck (East Indian walnut), in the fruit of Anacardium occidentale (Cashew), in the fruit of Areca catechu (Areca nut), in the fruit of Hydnocarpus wightianus (Hindi Chaulmoogra), in the rhizome of Rumex hymenosepalus (Arizona dock), in Zea mays (Corn) and in Ziziphus jujuba (Chinese date).[1]
Biosynthesis
In flavonoid biosynthesis in plants, the enzyme dihydrokaempferol 4-reductase converts aromadendrin to leucopelargonidin, using nicotinamide adenine dinucleotide phosphate (NADPH) as its cofactor.[2][3]

Leucopelargonidin can also be synthesized from aromadendrin in the laboratory by sodium borohydride reduction.[4]
Metabolism
Leucoanthocyanidin reductase transforms leucopelargonidin into afzelechin.[5][6]
