Influence of phytochemical composition on in vitro antioxidant and reducing activities of Indian ginseng [Withania somnifera (L.) Dunal] root extracts.

ABSTRACT:

Background

Roots of Withania somnifera (WS) are a celebrated medicinal ingredient in Ayurvedic and many other indigenous systems of medicine. The present study investigates the effect of the phytochemical composition of the extracts on their antioxidant and reducing activities.

Methods

WS roots were extracted with water, acetone, aqueous methanol (1:1), and methanol:chloroform:water (1:1:1) to obtain aqueous, acetone, hydro-methanolic, and methanol-chloroform-water extracts. Thereafter, phytochemical constitution and antioxidant and reducing activities of the extracts were compared using different qualitative and quantitative tests.

Results

Maximum extraction recovery was obtained with 50% aqueous methanol whereas extraction with acetone yielded the poorest rec
