Crocetin is an organic compound that is found in the saffron plant. It is a carotenoid that is responsible for the vibrant orange color of saffron. Crocetin is known for its various therapeutic properties, including anti-inflammatory and anti-cancer activity. While the word crocetin is commonly used, there are also synonyms for this compound such as crocin, safranal, and picrocrocin. These synonyms are often used interchangeably to refer to the same compound. Crocin, in particular, is a water-soluble carotenoid that is also found in the saffron plant and is closely related to crocetin. Safranal is the compound responsible for the distinct flavor and aroma of saffron.
