Wikipedia
Crocin is a natural drug carotenoid chemical compound that is found in the flowers crocus and gardenia. It is the diester formed from the disaccharide gentiobiose and the dicarboxylic acid crocetin. It has a deep red color and forms crystals with a melting point of 186 °C. When dissolved in water, it forms an orange solution.
Crocin is the chemical ingredient primarily responsible for the color of saffron.
The crocin underlying saffron's aroma is α-crocin (a carotenoid pigment that may comprise more than 10% of dry saffron's mass.) : trans- crocetin di-(β-D- gentiobiosyl) ester; it bears the systematic (IUPAC) name 8,8-diapo-8,8-carotenoic acid.
Crocins themselves are a series of hydrophilic carotenoids that are either monoglycosyl or diglycosyl polyene esters of crocetin.
The major active ingredient of saffron is the yellow pigment crocin 2 (three other derivatives with different glycosylations are known) containing a gentiobiose (disaccharide) group at each end of the molecule. The five major biologically active ingredients of saffron, namely the four crocins and crocetin, can be measured with HPLC-UV.
