Abstract

Twenty-six iridoids, including six undescribed ones (iridoidvols A−F) and an undescribed natural one, along with ten known sesquiterpenoids were isolated from the roots and rhizomes of Valeriana officinalis. Structurally, iridoidvol A is the first example of iridoid with sesquiterpenoid acid ester. In addition, all of the isolates were evaluated for anti-inflammatory and anti-influenza virus activities. Among them, isovaltrate isovaleroyloxyhydrin exhibited a significant inhibitory effect on NO production with an IC50 value of 19.00 μM.
