Morinda tinctoria commonly known as Indian Mulberry is a species of flowering plant in the family Rubiaceae which plays important role in traditional medicine. In the present study, the various anatomical characteristics and proximate analysis of root-bark and fruit of Morinda tinctoria were investigated by the microscopic sectioning using standard pharmacopoeia methods. Microscopic examination of the root-bark indicated the presence of calcium oxalate crystals of raphide bundles in the axial parenchyma. Calcium oxalate crystals were also present in the fruit, either as a 4-lobed druse type or as a spindle shaped Raphide type. Proximate analysis was carried out to evaluate the plant as a potential source of active compounds which could be served as potent drug or to develop novel insecticide against the major pest which involve in crop damage. A lower acid insoluble ash content was recorded for the fruit than the root-bark. Acid insoluble ash value of M. tinctoria fruit (0.510%) shows that small amount inorganic compound is insoluble in acid and therefore the fruit may be readily digested and absorbed when consumed.
