Regulatory evidence across markets

None of the 13 markets tracked here holds an imported rule under the name AMYRINS.

That is a statement about this inventory, not about the law: no imported rule is not evidence that a substance is permitted. A rule may exist under a different name, under a CAS or EC number this glossary entry does not carry, or in a dataset not yet imported.

Beta-Amyrin

Beta-amyrin is a pentacyclic triterpenoid that is oleanane substituted at the 3beta-position by a hydroxy group and containing a double bond between positions 12 and 13. It is one of the most commonly occurring triterpenoids in higher plants. It has a role as a plant metabolite and an Aspergillus metabolite. It is a pentacyclic triterpenoid and a secondary alcohol. It derives from a hydride of an oleanane. — ChEBI
