Valeriana officinalis (valerian), as a nutraceutical herb, is widely used for its sedative and hypnotic properties. It is known that C15 sesquiterpenoid valerenic acid (VA) is active ingredient responsible for pharmacological effects of V. officinalis. To evaluate the effect of methyl jasmonate (MeJA) concentrations (50 and 100 µM) in the modulation of expression patterns of the genes involved ...

Valeriana fauriei (V. fauriei), which emits a characteristic and unpleasant odor, is important in traditional medicine. In this study, the expression of terpenoid biosynthetic genes was investigated in different organs that were also screened for volatile compounds including valerenic acid and its derivatives. Specific expression patterns from different parts of V. fauriei were observed using q...

Although GABA neurotransmission has been suggested as a mechanism for Valeriana officinalis effects, CNS depression can also be evoked by inhibition of ionotropic (iGluR) and metabotropic glutamate receptors (mGluR). In this study, we examined if aqueous valerian extract interacted with glutamatergic receptors. Freshly prepared aqueous valerian extract was incubated with rat cortical synaptic m...

The present study investigated the effects of valerian methanolic extract and valerenic acid on expression LL-37 gene protein in A549 MRC5 line cells. After preparing Valerian seeds, sowing them March 2020, harvesting rhizome October was prepared from by maceration method. content determined using high performance liquid chromatography (HPLC). Two cell lines (A549 MRC-5) were used to extract, M...

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...

Valerian (Valeriana officinalis L.) is an important medicinal plant that is widely exploited for its roots and rhizomes which contain valepotriates and valerenic acids (with putative pharmacological activities). Thus root proliferation of valerian is very important. The aim of this study was to establish a practical tissue culture method for rapid and large-scale induction of V. officinalis L. ...
