The bioactive component harpagoside was successfully separated from the crude extract of Scrophularia ningpoensis Hemsley by one-step purification using high-speed counter-current chromatography (HSCCC). A two-phase solvent system containing n-butanol:ethyl acetate:water (1:9:10) was selected following consideration of the partition coefficient of

The cognitive-enhancing activities of E-harpagoside and 8-O-E-p-methoxycinnamoylharpagide (MCA-Hg) isolated from Scrophularia buergeriana were evaluated in scopolamine-induced amnesic mice by the Morris water maze and by passive avoidance tests. E-harpagoside and MCA-Hg significantly improved the impairment of reference memory induced by
