Outline
Three sesquiterpenoids and nine iridoids were isolated from the roots and rhizomes of Valeriana jatamansi by various chromatographic methods. Their structures were identified by physicochemical properties, NMR and MS data. Among them, valeriananoid G (1) was a new patchoulol-type sesquiterpenoid, and compound 3 was isolated from the genus Valeriana for the first time. Compounds 3 and 10 exhibited significant inhibitory effects on nitric oxide production induced by lipopolysaccharide in RAW 264.7 macrophages, with IC50 values of 19.00 and 3.66 μmol·L-1, respectively. In addition, compounds 4, 6 and 12 showed anti-influenza virus activity with IC50 values of 51.75, 51.40 and 102.08 μmol·L-1, respectively.
