• Uses: (+)-Vernolic Acid Methyl Ester, is a derivative of Vernolic Acid (E589430), which is the cis epoxide derived from the C12–C13 alkene of linoleic acid, and an isomer of coronaric acid. Vernolic acid is the key component in vernonia oil, which is produced in abundance by the genera Vernonia and Euphorbia and is a potentially useful biofeedstock.
