Sambubiose

Sambubiose is a disaccharide. It is the β--xylosyl-(1→2)-β--glucose.
Sambubiose is a component of some glycoside pigments. The fruits of "Viburnum dentatum" appear blue. One of the major pigments is cyanidin 3-sambubioside, but the total mixture is very complex. Sambubiosides with anthocyanidins can also be found in "Matthiola incana".
