Anti-inflammatory secoiridoid glycosides from Gentianella azurea
Bioorganic & Medicinal Chemistry Letters, 2014A phytochemical investigation on crude extract of Gentianella azurea led to the isolation of ten new (1-10) and one known (11) secoiridoid glycosides. Their structures were unambiguously elucidated by analysis of 1D and 2D NMR. Compounds 2, 5 and 11 were found to inhibit nitric oxide (NO) production in RAW 264.7 macrophages with IC50 values of 52.78 ...
