Natural Product Identification
Common NameLimonexic acid
DescriptionLimonexic acid, also known as limonexate or limonexin, belongs to the class of organic compounds known as limonoids. These are highly oxygenated, modified terpenoids with a prototypical structure either containing or derived from a precursor with a 4,4,8-trimethyl-17-furanylsteroid skeleton. All naturally occurring citrus limonoids contain a furan ring attached to the D-ring, at C-17, as well as oxygen containing functional groups at C-3, C-4, C-7, C-16 and C-17. Limonexic acid is an extremely weak basic (essentially neutral) compound (based on its pKa). Outside of the human body, limonexic acid has been detected, but not quantified in, citrus and sweet oranges. Limonexic acid is found in Citrus aurantium, Citrus spp. and Dictamnus angustifolius. This could make limonexic acid a potential biomarker for the consumption of these foods.
