Chemical compound
Vicianose is a disaccharide.
Vicianin is a cyanogenic glycoside containing vicianose. The enzyme vicianin beta-glucosidase uses (R)-vicianin and water to produce mandelonitrile and vicianose.
The fruits of Viburnum dentatum appear blue. One of the major pigments is cyanidin 3-vicianoside, but the total mixture is very complex.[1]
