Natural Product Identification
Common NameCrocin 4
DescriptionCrocin 4, also known as macrocin, belongs to the class of organic compounds known as diterpenoids. These are terpene compounds formed by four isoprene units. Crocin 4 is an extremely weak basic (essentially neutral) compound (based on its pKa). Outside of the human body, Crocin 4 has been detected, but not quantified in, herbs and spices and saffrons. Crocin 4 is found in Streptomyces fradiae. This could make crocin 4 a potential biomarker for the consumption of these foods.
