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
