| Common Name | Obtusilactone A |
|---|
| Description | Obtusilactone A belongs to the class of organic compounds known as tetrahydrofurans. These are heterocyclic compounds containing a saturated, aliphatic, five-membered ring where a carbon is replaced by an oxygen. Obtusilactone A has been detected, but not quantified in, herbs and spices. This could make obtusilactone a a potential biomarker for the consumption of these foods. Based on a literature review a significant number of articles have been published on Obtusilactone A. |
