| Common Name | Kuwanol C |
|---|
| Description | Kuwanol C belongs to the class of organic compounds known as pyranoflavonoids. Pyranoflavonoids are compounds containing a pyran ring fused to a 2-phenyl-1,4-benzopyran skeleton. Thus, kuwanol C is considered to be a flavonoid. Kuwanol C has been detected, but not quantified in, fruits. This could make kuwanol C a potential biomarker for the consumption of these foods. Based on a literature review very few articles have been published on Kuwanol C. |
