Glycyrrhizin contributes sweetness in taste but is not the volatile source of a liquorice perfume smell. Anise-like accords may use anethole-containing materials, alongside woody and gourmand elements. Anethole is an aromatic ether associated with the characteristic smell of anise-like materials, not a synonym for liquorice root. Separating taste-active nonvolatile compounds from aromatic volatiles helps explain why a root extract and a black-liquorice accord may smell different.
