Some pharmacognostical characteristics of tragia involucrata linn. Roots.

The macroscopical characters of the roots, physical constant values, extractive values, colour, consistency and extractive values with different solvents, behaviour on treatment with different chemical reagents, fluorescence characters of liquid extracts and root powder after treatment with different chemical reagents under ultraviolet light of the powdered roots of Tragia involucrata Linn. (Fam Euphorbiaceae) were studied to fix some pharmacognostical parameters which will enable the future investigators for indentification of the plant. Preliminary phytochemical study on different extracts of the roots were also preformed.
