| Common Name | Coumarinic acid |
|---|
| Description | Coumarinic acid, also known as cis-o-coumaric acid or cis-o-hydroxycinnamic acid, is a hydroxy derivative of cinnamic acid. Cinnamic acid and its derivatives are used as important components in flavours, perfumes, synthetic indigo, and pharmaceuticals. There are three isomers of coumaric acid: o-coumaric acid, m-coumaric acid, and p-coumaric acid. These isomers differ by the position of the hydroxy substitution. p-Coumaric acid is the most abundant isomer in nature (Wikipedia ). Coumarinic acid is found in pomegranate. |
