-Of the ca. 250 constituents identified in clary sage oil, (R)-linalyl acetate (67%) and (R)-linalool (16%) represent the main part of the oil, but the odor of the oil is based on trace compounds. Some cyclic ethers (pyranes) possess camphoraceous odors. Sesquiterpene derivatives play an important role: (3R,6E)-3,15-epoxy-caryophyll-6-ene (woody), β-caryophyllene oxide (woody), (+)-spathulenol (aromatic earthy), (+)-isospathulenol (aromatic earthy), 1,5-epoxy-salvial-(4,14)-ene (spicy floral, stronger than its thia analog mint sulfide), α-bisabolol (floral), 10-epi-ɣ​-eudesmol (woody), salvial-4(14)-ene-1-one (woody), (-)-ambrox (ambergris), and sclareol oxide (ambergris). The labdanoid diterpenediol (-)-sclareol (2% in clary sage oil, 70% in its absolute) is isolated from oil or absolute on industrial scale as starting material for th synthesis of (-)-ambrox. \\+| {{:linalool_r.jpg| (R)-(-)-linalool }} \\ (R)-(-)-linalool | {{:linalylacetate_r.jpg| linalyl acetate }} \\ (R)-(-)-linalyl acetate | {{:spathulenol_plus.jpg|(+)-spathulenol}} \\ (+)-spathulenol | {{:ambrox.jpg|(-)-ambrox}} \\ (-)-ambrox |
