To analyze the pharmacognostic characteristics and physicochemical parameters of the root of Eranthemum nigrum (E. nigrum). Microscopic characters and powder analysis had been carried out with the help of a microscope. The physicochemical properties such as loss on drying, total ash value, acid insoluble ash value, water-soluble ash value, extractive values, and fluorescence of E. nigrum had been performed. The color, shape, size, odor, and surface characteristics were reported from the root and powdered root material of E. nigrum. Light microscope images of cross-section and powdered root revealed lignified xylem fibers, xylem vessels, cork cells, and parenchyma cells. Phytochemical testing confirmed steroids, alkaloids, tannins, saponins, carbohydrates, glycosides, amino acids, and proteins. Physicochemical parameters such as moisture content, ash value, extractive value, and fluorescent behavior of root powder have also been established. The morphological, microscopical, and physicochemical parameter results provided in this paper may be utilized as a basis for the preparation of a monograph on E. nigrum root.
