| Common Name | Isomorellic acid |
|---|
| Description | Isomorellic acid, also known as isomorellate or butyl caproate, belongs to the class of organic compounds known as pyranoxanthones. These are organic aromatic compounds containing a pyran or a hydrogenated derivative fused to a xanthone ring system. Isomorellic acid has been detected, but not quantified in, fruits and herbs and spices. This could make isomorellic acid a potential biomarker for the consumption of these foods. Based on a literature review very few articles have been published on Isomorellic acid. |
