Crocin is a natural carotenoid chemical compound that is found in the flowers crocus and gardenia.[1] 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.

Physiological effects[edit]

Crocin has been shown to be a potent neuronal antioxidant.[2][3][4] It has also been shown to have an antiproliferative action against cancer cells in vitro.[5][6][7] Limited evidence suggests possible antidepressant properties of crocin in mice[8] and humans.[9] One study reports aphrodisiac properties in male rats at very high doses.[10]
