ABSTRACT

Background:

Shankhpushpi is an Ayurvedic drug, widely used for its actions on the central nervoussystem, especially to improve intellect and boost memory. Four botanicals viz. Canscora decussata Schult.(CD), Clitorea ternatea Linn. (CT), Convolvulus pluricaulis Choisy. (CP) and Evolvulus alsinoides Linn. (EA)are considered as sources of Shankhpushpi by Indian practitioners on the basis of their morphologicaldescriptions given in ancient texts.

Objective:

The present study was undertaken to evaluate the neuropharmacological effect of four herbscommonly identified as source of Shankhpushpi.Materials and

methods:

Methanol extracts of all four varieties were tested and evaluated in vitro and invivo for their neuropharmacological effects. Experiments such as protection against b-amyloid inducedneurotoxicity on brain cell line (Neuro 2A), antioxidant potential, AchE (acetylcholinesterase enzyme)inhibition, and 5-LOX (lipoxygenase) enzyme inhibition were conducted for in vitro evaluation. For in vivoevaluation, scopolamine (0.3 mg/kg i.p.) induced memory retrieval using pole climbing apparatus andMorris water maze were performed in rat models.

Results:

It was found that protective effects of EA and CD against b-amyloid induced neurotoxicity inNeuro 2A cells were significantly higher than CT and CP. EA proved to be superior than other varieties onthe basis of antioxidant activity, AchE inhibitory and LOX inhibitory activities. The preventive activity ofEA on scopolamine induced memory retrieval in pole climbing and Morris water maze task in rats wasfound to be higher than that of CD, CT and CP.

Conclusion:

EA has remarkable neuropharmacological effect as compared to other three varietiesof Shankhpushpi. This effect may be attributed due to the presence of steroids (stigmasterol and betulinicacid), coumarins (scopoletin) and flavonoids (b-carotene and chlorogenic acid). Hence it can be used as apromising lead in development and management of neuronal disorders including Alzheimer's disease.© 2017 Transdisciplinary University, Bangalore and World Ayurveda Foundation.
