| Common Name | Crocin I |
|---|
| Description | Crocin, also known as alpha-crocin or saffron, belongs to the class of organic compounds known as diterpenoids. These are terpene compounds formed by four isoprene units. Crocin is an extremely weak basic (essentially neutral) compound (based on its pKa). Note that in India, the term 'Crocin' is also used by GlaxoSmithKline as a brand-name for paracetamol. A diester that is crocetin in which both of the carboxy groups have been converted to their gentiobiosyl esters. Crocin I is found in Buddleja officinalis, Crocus sativus and Gardenia jasminoides. Crocin I was first documented in 2003 (PMID: 14514073). It is one of the water-soluble yellow-red pigments of Crocin and is used as a spice for flavouring and colouring food (PMID: 17215084) (PMID: 16448211) (PMID: 17704979) (PMID: 21398065). |
