Five new compounds including five iridoids (1-5) and six known compounds were isolated from the rhizomes of Scrophularia ningpoensis. Their structures were determined by extensive NMR and IR, MS spectroscopic data analyses. The anti-inflammatory, antibacterial, antifungal, and cytotoxic activities of the isolated compounds were evaluated. Compound 11 exhibited significant inhibitory effects on lipopolysaccharide-induced nitric oxide production in RAW264.7 macrophage cells.
