+ | ... if it is assumed that the volatile oil content of the root is high (e.g., 2.8%), and little bornyl acetate is present, some 30 to 40% of the volatile oil (i.e., ∼0.9% of the root), might be capable of yielding isovaleric acid. An additional small isovalerate contribution might be found from the breaking down of valepotriates. Hence up to a total of 1% of the root might be converted to isovalerate. It is very likely that isovaleric acid possesses anticonvulsant properties..." \\ | ||

- | "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%).
