- | The flower scent of living V.officinalis does not contain the unpleasant smelling valeric acid or isovaleric acid which are major components of the hydrodistilled flower oil. Headspace samples from unpicked valerian flowers contained lavandulyl isovalarate (15.0%), lavandulyl 2-methylbutyrate (0.6%), and lavandulol (1.6%), (E,E)-alpha-farnesene (7.6%), 3, | + | **flowers** \\ |

+ | Among the many sesquiterpenoid compounds present in V.officinalis root oil, (-)-maaliol sticks out: The higher the content, the finer the character of the scent of the oil. The actual scent carrier proved to be the ester of isovaleric acid with (-)-myrtenol. In addition, the acetates of (-)-myrtenol and (-)-borneol play an olfactory role. \\ | ||

- | "The volatile constituents from roots of Valeriana officinalis L. were investigated using GC and GC/MS methods. Valerianae radix samples were obtained from retail pharmacies of different European countries. The roots of 15 V. offcinalis samples yielded 0.19–1.16% essential oil on a dry weight basis. The basic oil components among the identified 86 compounds were bornyl acetate (2.9–33.7%), α-fenchene (0–28.3%), valerianol (0.2–18.2%), valerenal (tr-15.6%), isovaleric acid (0–13.1%), camphene (0–11.1%) and valeranone (0.5–10.9%).
