| | The essential oils of the two varieties C.ladanifer var.maculatus (with red marks on the white corolla) and C. ladanifer var.albiflorus (without red marks) contained the same major components. \\ |
| | "Essential oils of the three populations of Cistus ladanifer var. maculatus have significantly higher concentrations in α-pinene, β-pinene, γ-terpinene, verbenone than the oils from the three populations of Cistus ladanifer var. albiflorus. The latter oils have significantly lower concentrations of benzaldehyde, p-cymen-8-ol, ledol and viridiflorol than the oils of Cistus ladanifer var. maculatus. These differences can not be attributed to differences in environmental conditions..." \\ |

| "Labdanum oil is a mixture of ca. 250 compounds... Only ten compounds, i.e., (-)α-pinene, (+)-camphene, pinocarveol, bornyl acetate, borneol, 2,2,6-trimethylcyclohexanone, (Z)-ocimenone, (-)-allo-aromadendrene/(+)-ledene, (+)-ledol, and viridiflorol, occur in concentrations above 1%, however, these do not represent the complex odor profile of the oil. The odor character of labdanum oil is on the contrary determined by a large number of oxygenated trace compounds such as [[http://de.wikipedia.org/wiki/Ambrox|(-)-ambrox]], 6-oxoisoambrox and a decahydronaphthalenol, which are responsible for the distinct ambery character... The smoky-leathery notes and the animalic undertones are caused by a complex of 25 phenols (1.5%)... The character-impact compound of oakmoss, methyl beta-orcinolcarboxylate, is responsible for the powdery, moss-like undertones... Another constituent, 2-methyloctanoic acid, has a strong labdanoic odor on its own, (and) 3,4,4-trimethylcyclopentane-1,2-dione... has a strong celery aroma." \\ | "Labdanum oil is a mixture of ca. 250 compounds...
