%X The transverse section of stem, root and leaf of Amaranthus spinosus Linn. was done with the help of sharp blade and double staining. The anatomy of stem and roots showed cellular differentiation. Both the stem and root showed secondary growth. In stem, the vascular bundle pattern is conjoint, collateral and endarch type; whereas root showed conjoint, collateral and exarch type of vascular bundle. Leaf anatomy showed kranz mesophyll. Endodermal wall is covered with casperian strips. The stomata (S) occurred on both adaxial and abaxial leaf surfaces. The stomata were found to be anomocytic type. Powdered drug, treated with different chemicals and its extracts with different solvent showed colour changes when illuminated with UV light.
