| Common Name | (all-E)-Crocetin |
|---|
| Description | (all-E)-Crocetin, also known as trans-crocetin, belongs to the class of organic compounds known as acyclic diterpenoids. These are diterpenoids (compounds made of four consecutive isoprene units) that do not contain a cycle. Based on a literature review a small amount of articles have been published on (all-E)-Crocetin. |
