They are traditionally used for curing blood disorders, skin diseases, as anti-inflammatory, haemostatic, urolithotriptic, antipyretic, analgesic, anthelmintic and for improving complexion. They are found in several important traditional medicinal formulations and hold a great export potential as well. However, stems of Rubia tinctorum L. are also available in the Indian market, which are not official and have been found to contain lucidin, a genotoxic compound. The present investigation deals with comparative pharmacognostical study of stems of both species and establishment of various quality parameters. Morphologically, the stems of both the species vary a lot. Transverse section of both stems showed the presence of reddish dye in cortex and acicular crystals of calcium oxalate; however, the width of cork, cortex, stele and pith varied. Powder microscopy revealed the presence of annular and pitted xylem vessels, xylem fibers and acicular crystals in singular and bundles; however their sizes varied in both species. From the phytochemical screening, the detected phyto-constituents were estimated by their respective procedures, which also varied in both species. Thus, the present work can serve as a very useful botanical and phytochemical tool in the identification, authentication and standardization of the raw material and prepared formulations of R. cordifolia L. and distinguishing it from of R. tinctorum L., which will consequently benefit the herbal industries and traditional medicinal healers.
