(Ginger) is an Indian ornamental plant, belonging to family Costaceae. The present research work deals with the establishment of standardization parameter regarding comparative pharmacognostic study between <em>Costus speciosus</em> and <em>Zingiber officinale</em> rhizome.</p><p><strong>Methods: </strong>Macroscopic and microscopic evaluation, physicochemical parameters like ash values, moisture content, extractive value, fluorescence analysis and the preliminary phytochemical investigation was done.</p><p><strong>Results: </strong>The Macroscopic difference was found as an absence of odor and taste in <em>Costus speciosus</em> and presence of pungent and aromatic odor in <em>Zingiber officinale</em>. Oil globule, tracheids, starch granules in <em>Zingiber officinale</em> was found whereas the absence of the same in <em>Costus speciosus</em> rhizome was found in the microscopic evaluation. Fluorescence study also exhibits differences. The presence of saponin, carbohydrate, glycosides in <em>Costus speciosus</em> whereas <em>Zingiber officinale</em> revealed the presence of alkaloids, glycosides, flavonoids and protein.</p><strong>Conclusion: </strong>These finding can serve as the basis for Identification and investigation of <em>Costus speciosus</em> and <em>Zingiber officinale</em> rhizome and can also establish the characteristic differentiating features of both.}, number={4}, journal={International Journal of Current Pharmaceutical Research}, author={Kala, Chandra and Ali, Syed Salman and Chaudhary, Sudhir}, year={2016}, month={Oct.}, pages={19–23} }
