Rutinose is a disaccharide and carbohydrate , which is composed of glucose and rhamnose with an α (1 → 6) bond. Rutinose produced during the hydrolysis of rutin with the enzyme Rhamnodiastase and was first reported by M. Schubert 2002. datisca isolated.

Occurrence

Rutinose is part of the glycoside hesperidin , which is found in the peel of oranges and lemons .

With quercetin , rutinose forms the glycoside rutin , which is found in many plants to protect against UV radiation .
