scrophularia deserti/amnesia

OBJECTIVE The cognitive-enhancing and antioxidant activities of KD-501, a standardized extract of the roots of Scrophularia buergeriana Miquel (Scrophulariceae) were investigated. METHODS KD-501 was orally administered to amnesic mice induced by scopolamine and we performed passive avoidance and the

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

We previously reported that phenylpropanoids isolated from the roots of Scrophularia buergeriana Miquel (Scrophulariaceae) protected cultured cortical neurons against glutamate-induced neurotoxicity [Kim and Kim, Phytochemistry, 54 (2000) 503-509; Kim et al., Br. J. Pharmacol. 135 (2002) 1281-1291].
