Description
Summary:Catharanthus roseus (L.) G. Don of the family Apocynaceae is a native of Madagascar and now found commonly throughout India. The species has been cultivated for herbal medicine as well as a garden plant. It is a rich source of alkaloidal constituents. The alkaloids vinblastine and vincristine extracted from the plant are used in the treatment of leukemia and Hodgkin's disease. The entire plant is used in many disorders like diabetes, malaria, hypertension, heart disease in many countries. The present investigation deals with microscopic evaluation of white and pink forms of Vinca rosea root. Both these plants have same medicinal value, so in this study, the authors have observed if there any differential characters are present or not particularly in the root. A detailed pharmacognostic study of drug samples was carried out which highlighted certain diagnostic macro and microscopic characters useful for their identification. Such study would serve as a useful gauge in standardization of the root material and ensuring quality formulations.
