ABSTRACT
Today, World over, there is a great deal of interest in Ayurvedic system of medicine and thus the demand for various medicinal plants in the production of Ayurvedic medicines is ever increasing. Due to varied geographical locations where these plants grow, a great deal of adulteration or substitution is encountered in the commercial markets. Histological studies of the plant drugs are not only to study the adulterants but also are indispensable in accurate identification. Microscopic observations of the Phyllanthus species revealed the occurrence of anisocytic and paracytic type of stomata in Phyllanthus amarus , while only anisocytic type of stomata is present in P. fraternus and P. maderaspatensis. Epidermal cell walls of P. amarus and P. fraternus are wavy and straight walled epidermal walls are observed in P. maderaspatensis. In India all the above-mentioned species of Phyllanthus are called "Bhumyamalaki" and they are being used in the treatment of various liver disorders. However, all the species of Phyllanthus doesn't have the active constituents responsible for the treatment of liver disorders. In the present investigation by using simple micro techniques accurate identification of different species of Phyllanthus has been established.
