Abstract

The medicinal plant Withania somnifera, usually referred to as Ashwagandha, is a member of the Solanaceae family. The presence of Withanolides in the roots is responsible for a number of pharmacological effects in Ashwagandha. Withanolides have been demonstrated to be an effective neuronal, immune, anti-stress, and anti-cancer agent. However, Withanolides demonstrated limited permeability, lowering the bioavailability and efficacy of active compounds. The goal of the study was to ascertain the biological efficacy of Ashwagandha Composition, a blend of W. somnifera milk extract and water extract (1:1) with a high concentration of Withanolides (3-5%), at lower dosages with improved bioabsorption compared to pure Ashwagandha Hydro ethanolic extracts fortified with 2.5% withanolides. The W. somnifera Composition was assessed for its bioabsorption and bioefficacy by exploring its intestinal absorption capacity, Acetylcholinesterase Inhibition (82%), antioxidant potential (91%), glutathione reduction potential (15.6%), anti-inflammatory activity (87.2%), and anti-cancer activity. Additionally, Ashwagandha Composition was also evaluated for its safety profile. We found W. somnifera Composition (1:1) is more bioavailable and showed higher biological activity than the Ashwagandha Hydro ethanolic extract fortified with 2.5% withanolides (Ashwagandha extract). Hence, the W. somnifera a Composition can be used as a therapeutic medication once its safety concerns are addressed by in vivo trials.
