Crocin
Crocin-1 is a diester that is crocetin in which both of the carboxy groups have been converted to their gentiobiosyl esters. It is one of the water-soluble yellow-red pigments of saffron and is used as a spice for flavouring and colouring food. Note that in India, the term 'Crocin' is also used by GlaxoSmithKline as a brand-name for paracetamol. It has a role as an antioxidant, a plant metabolite, a histological dye and a food colouring. It is a diterpenoid, a diester and a disaccharide derivative. It is functionally related to a gentiobiose and a beta-D-gentiobiosyl crocetin. — ChEBI
