A new sesquiterpene, named valeriene (1), along with three iridoids, namely valepotriate (2), dihydrovaltrate (3) and acevaltrate (4) were isolated from the ethyl acetate extract of Valeriana pseudofficinalis roots. The structures of these compounds were determined by 1D and 2D NMR, MS techniques, and X-ray single crystal diffractometry. This is the first report of the chemical components isolated from this plant.
