This article is about a naturally occurring compound. For the Indian brand of painkiller of same name, see paracetamol.

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. It has also been shown to be a potent antioxidant. [2] [3] [4] It has also been shown to have an anticarcinogenic action. [5] [6] [7] Crocin has been shown to have antidepressant properties.[8][9]
