Kaurenoic acid
IUPAC 名称
5,9-dimethyl-14-methylidenetetracyclo[11.2.1.0¹,¹⁰.0⁴,⁹]hexadecane-5-carboxylic acid
描述
Kaurenoic acid, also known as kaur-16-en-18-oic acid or kaurenoate, 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. Kaurenoic acid is practically insoluble (in water) and a weakly acidic compound (based on its pKa). Kaurenoic acid can be found in sunflower, which makes kaurenoic acid a potential biomarker for the consumption of this food product.
