In vitro study on the interaction of Valeriana officinalis L. extracts and their amino acids on GABAA receptor in rat brain.

Author information

Laboratory of Pharmacology, Faculty of Medicine, University of Coimbra, Portugal.


This work studied in vitro the interaction of aqueous and hydroalcoholic extracts of Valeriana officinalis L. and compounds that are present in the extracts (amino acids and valerenic acid) with the GABAA (gamma-aminobutyric acid) receptor, using the [3H] muscimol binding technique to crude synaptic membranes from rat brain cortices. Both extracts displaced [3H]muscimol bound and this effect is probably due only to their amino acid content, specially GABA. This fact explains the in vitro effect of valerian extracts on GABAA receptor but not their sedative effect.
