Abstract
Investigation into the chemical diversity of Nardostachys chinensis Batal led to the discovery of three new (1–3) and one known (4) iridoid glycosides. Their structures were established through spectroscopic methods including 1 D and 2 D NMR experiments and HRESIMS analysis. Inhibitory effects of 1–4 on nitric oxide production were investigated in lipopolysaccaride (LPS)-mediated RAW 264.7 cells, and they displayed IC50 values in the range 7.8–15.2 μM.
