-"The analysis of the volatile components in the essential oil of Salvia sclarea L. (Labiatae) by GC and GC-MS demonstrated the presence of at least 72 compounds. They correspond to 97.2% of the oil. The major compounds were linalool, linalyl acetate, terpineol, neryl acetate, geraniol, geranyl acetate, nerol, and [[http://de.wikipedia.org/wiki/Sclareol|sclareol]]." \\+"The analysis of the volatile components in the essential oil of Salvia sclarea L.

 Major constituents of the essential oil of fresh inflorescences were linalyl acetate (39.6%), linalool  (28.8%), α-terpineol (5.6%), sclareol (2.4%), geraniol (2.1%), geranyl acetate (2.3%), (E)-β-ocimene    (2.5%), myrcene (1.7%), neryl acetate (1.1%) and limonene (1.0%). Mminor constituents were e.g. camphor (0.1%), (Z)-linalool oxide (0.1%) and terpinen-4-ol (0.6%). \\ Major constituents of the essential oil of fresh inflorescences were linalyl acetate (39.6%), linalool  (28.8%), α-terpineol (5.6%), sclareol (2.4%), geraniol (2.1%), geranyl acetate (2.3%), (E)-β-ocimene    (2.5%), myrcene (1.7%), neryl acetate (1.1%) and limonene (1.0%).

 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 ɣ​-bicyclohomofarnesal (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 the synthesis of (-)-ambrox. \\ 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.
