| Common Name | 5,4′-dihydroxy-3,7-dimethoxyflavone |
|---|
| Description | Kumatakenin belongs to the class of organic compounds known as 7-o-methylated flavonoids. These are flavonoids with methoxy groups attached to the C7 atom of the flavonoid backbone. Thus, kumatakenin is considered to be a flavonoid lipid molecule. 5,4′-dihydroxy-3,7-dimethoxyflavone was first documented in 2026 (PMID: 41617685). Kumatakenin is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral. |
