Metabolite Identification
Common NameCiliaric acid
DescriptionCiliaric acid, also known as ciliarate, is a member of the class of compounds known as kaurane diterpenoids. Kaurane diterpenoids are diterpene alkaloids with a structure that is based on the kaurane skeleton. Kaurane is a tetracyclic compound that arises by cyclisation of a pimarane precursor followed by rearrangement. It possesses a [3,2,1]-bicyclic ring system with C15-C16 bridge connected to C13, forming the five-membered ring D. Ciliaric acid is practically insoluble (in water) and a weakly acidic compound (based on its pKa). Ciliaric acid can be found in sunflower, which makes ciliaric acid a potential biomarker for the consumption of this food product.
