Comparative antioxidant potential of Withania somnifera based herbal formulation prepared by traditional and non-traditional fermentation processes

摘要

BackgroundAshwagandharishtha is a liquid polyherbal formulation traditionally prepared by fermentation process using the flowers of Woodfordia fruticosa. It contains roots of Withania somnifera as a major crude drug. Alcohol generated during the fermentation causes the extraction of water insoluble phytoconstituents. Yeasts present on the flowers are responsible for this fermentation.
