Common Name | Nomilin |

Description | Nomilin 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. Nomilin is an extremely weak basic (essentially neutral) compound (based on its pKa). Nomilin is a bitter tasting compound. Outside of the human body, nomilin has been detected, but not quantified in, several different foods, such as citrus, lemons, mandarin orange (clementine, tangerine), and sweet oranges. Nomilin is found in Azadiractica indica, Citrus aurantium, Citrus depressa, Citrus erythrosa , Citrus hanaju, Citrus hystrix, Citrus cavaleriei, Citrus junos, Citrus maxima, Citrus medica, Citrus natsudaidai, Citrus paradisi L. , Citrus sphaerocarpa, Citrus spp., Citrus tamurana, Citrus tamurana Hort. , Citrus tangemna, Citrus unshiu Markovich , Ciyrus junos, Microula sikkimensis, Phellodendron amurense and Skimmia japonica. This could make nomilin a potential biomarker for the consumption of these foods. |
