Variation in the composition of the essential oil of Valeriana officinalis L. roots from Estonia
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 or cultivated in Estonia. The roots of five V. officinalis samples yielded 0.28–1.16% essential oil in the cut drug, which usually corresponded (four samples) to the European Pharmacopeia standard (0.3%). The basic oil compo...
متن کاملRoot colonization by symbiotic arbuscular mycorrhizal fungi increases sesquiterpenic acid concentrations in Valeriana officinalis L.
In some medicinal plants a specific plant-fungus association, known as arbuscular mycorrhizal (AM) symbiosis, increases the levels of secondary plant metabolites and/or plant growth. In this study, the effects of three different AM treatments on biomass and sesquiterpenic acid concentrations in two IN VITRO propagated genotypes of valerian ( VALERIANA OFFICINALIS L., Valerianaceae) were investi...

Therefore, the current study was undertaken in an attempt to increase the use of these drugs without causing nephrotoxicity by exploring the nephroprotective effects of a medicinal plant with high flavonoid contents and strong antioxidant pro...
متن کاملEssential oil constituents of Valeriana italica and Valeriana tuberosa. Stereochemical and conformational study of 15-acetoxyvaleranone.
The chemical composition of the essential oils obtained by hydrodistillation of roots, stems with leaves and inflorescences of Valeriana italica Lam. and Valeriana tuberosa L. were studied by GC/MS. Seventy-three and forty-one constituents were identified from each plant, respectively. The major constituent of the oil obtained from the roots of V. italica was isolated and identified as 15-aceto...
