| Common Name | Guaiaretic acid |
|---|
| Description | (?)-Guaiaretic acid, also known as (?)-Guaiaretate, belongs to the class of organic compounds known as lignans, neolignans and related compounds. These are plant products of low molecular weight formed primarily from oxidative coupling of two p-propylphenol moieties. They can also be described as micromolecules with two phenylpropanoid units coupled together. They can be attached in various manners, like C5-C5', C8-C8'. Most known natural lignans are oxidized at C9 and C9´ and, based upon the way in which oxygen is incorporated into the skeleton and on the cyclization patterns, a wide range of lignans of very different structural types can be formed. Guaiaretic acid is found in Guaiacum officinale . Guaiaretic acid was first documented in 2009 (PMID: 21583141). Based on a literature review a small amount of articles have been published on (?)-Guaiaretic acid (PMID: 23915010) (PMID: 20000780). |
