Abstract: Ageing is characterized by the declined ability to respond to stress, reduced cellular functions and increased incidence of age related pathologies, like Senile Dementia of Alzheimer s Type (SDAT). The treatment of SDAT still remains a challenge, however converging evidences suggested that age associated neurodegeneration can actually be prevented by neuroprotective strategies. In this regard, the disease preventive and health promotive approach of and#8213;Ayurvedaand#8214; which involve the use of plant extracts alone or in combination may provide promising therapeutic benefits by promoting the healthy brain ageing, and preventing or delaying the susceptibility to develop SDAT. Although, the textual and experience based evidences regarding the efficacy of medicinal plants are abundant, limited experimental studies are available inorder to understand and validate their neuroprotective mechanism of action. In the present research work, bacosides (saponins) and curcuminoids (polyphenols) of Bacopa monnieri (L.) whole plant and Curcuma longa (L.) rhizomes respectively were investigated for their neuroprotective mechanism of action to promote and#8213;successful ageingand#8214; and prevent or delay the progression of SDAT in the aged Wistar rats. Bacosides and curcuminoids were extracted from the standard extract of Bacopa monnieri whole plant and Curcuma longa rhizomes respectively and quantified for their marker components by HPLC. The isolated bacosides and curcuminoids fractions were evaluated for their potential total antioxidant capacity, total NO scavenging and acetylcholinesterase inhibition activities in in-vitro assays and compared with respective standard. Bacosides and curcuminoids were subjected to in vivo studies where initially the optimum dose of both the putative drug candidates were determined by administering the drugs orally to aged Wistar rats for three months in dose dependant manner. The optimum dose of 200mg/kg and 100 mg/kg for bacosides and curcuminoids respectively were selected and was used for further experimentation
