DescriptionEnt-7α-hydroxykaur-16-en-19-oate 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. Ent-7α-hydroxykaur-16-en-19-oate is practically insoluble (in water) and a weakly acidic compound (based on its pKa). Ent-7α-hydroxykaur-16-en-19-oate can be found in a number of food items such as greenthread tea, cardamom, agave, and hickory nut, which makes ent-7α-hydroxykaur-16-en-19-oate a potential biomarker for the consumption of these food products.
