Popis: Coleus forskohlii (Willd.) Briq. is an important plant used against various disorders in indigenous systems of medicine, such as antiaging, antioxidant and as a remedy for heart, abdominal and respiratory disorders. In the present communication a detailed pharmacognostical study of roots of this plant procured from different geographical zones of India is carried out. Although all the samples show similar macroand microscopic characters, there is remarkable variation in the percentages of coleonol, sugars, starch and protein in different samples. For instance, the percentage of coleonol is higher in Salem (3.11%) and Vijaywadah (2.202%) as compared to Agrakhal (1.139%) and Tarikhet (0.7319%); similarly, there is an almost four fold increase in percentages of sugar and starch in southern samples while the protein percentage is almost twice as high in northern samples. Further, a variation in heavy metal concentration is also observed.
