- Abstract: OBJECTIVE: To study the chemical constituents in the roots of Scrophularia ningpoensis Hemsl. METHODSE: Compounds were isolated by chromatographic techniques and their structures were elucidated by spectral methods. The anti-inflammatory activities of all isolated compounds were evaluated by lipopolysaccharides (LPS)-stimulated BV2 cells model. RESULTS: Eighteen compounds were isolated and identified as 2'''-acetyl angroside C (1), saccatoside (2), 6-O-α-L-(2″-O-feruloyl)rhamnopyranosylcatalpol (3), scrophularioside (4), harprocumbide A (5), 6″-O-β-D-glucopyranosylharpagoside (6), harpagoside (7), 8-O-(p-coumaroyl)-harpagide (8), 8-O-feruloylharpagide (9), 6-O-α-D-galactopyranosylharpagoside (10), 6'-O-cinnamoylharpagide (11), angoroside B (12), angoroside C (13), scrophuloside B1 (14), 2-(3-hydroxy-4-methoxyphenyl)ethyl-O-α-L-arabinopyranosyl-(1→6)-O-α-L-rhamnopyranosyl-(1→3)]-β-D-glucopyranoside (15), darendoside B (16), 6-O-caffeoyl-β-D-fructofuranosyl-(2→1)-α-D-glucopyranoside (17), and sibirioside A (18). CONCLUSION: Compound 1 is new compound, and compounds 2-4, 12, 14, and 17 are isolated from this plant for the first time. Compounds 1, 12, and 13 show significant inhibition against nitric oxide production in LPS-stimulated BV2 cells model.
