Phytochemical Screening of Withania Somnifera, Antioxidant, & Antimicrobial Activities in Various Regions of North Bihar with Respect to Soil and Climate

Abstract

Withania somnifera (Ashwagandha) is a prominent medicinal plant with a wide range of therapeutic properties, attributed to its rich phytochemical profile. This study investigates the influence of soil composition and climatic conditions on the phytochemical content, antioxidant, and antimicrobial activities of Withania somnifera cultivated in different regions of North Bihar. Samples were collected from five distinct regions, each with varying soil types and microclimates. The phytochemical analysis revealed significant variations in the concentration of bioactive compounds, such as withanolides and flavonoids. Antioxidant and antimicrobial assays indicated that these variations are closely linked to the environmental conditions of each region. The findings suggest that region-specific cultivation practices could enhance the medicinal quality of Withania somnifera.
