Xanthoceraside rescues learning and memory deficits through attenuating beta-amyloid deposition and tau hyperphosphorylation in APP mice

Xanthoceraside, a triterpenoid saponin, has been shown to reverse cognitive deficits in several Alzheimer's disease (AD) animal models. However, the effects of xanthoceraside on the Aβ deposition pathology and the APP processing in AD are unclear. Here, we show that xanthoceraside at doses of 0.08 and 0.32 mg/kg/d for 6 months significantly improved learning and memory impairment in APP transgenic mice assessed by the Y maze and novel object...
