The present study focuses on the pharmacognostic characterization and phytochemical profiling of Cissampelos pareira roots to establish reliable diagnostic features for identification and standardization. C. pareira, a medicinal plant from the family Menispermaceae, is often erroneously identified as Cyclea peltata due to morphological similarities, highlighting the need for detailed microscopic evaluation. Macroscopic and microscopic analyses revealed distinctive features such as a multilayered cork, lignified stone cells, medullary rays, vascular strands, starch grains, and calcium oxalate crystals. Histochemical tests confirmed the presence of alkaloids, phenolics, mucilage, lignin, starch, and oils in specific tissues. Preliminary phytochemical screening of ethanolic root extracts indicated the presence of alkaloids, flavonoids, glycosides, steroids, sterols, tannins, terpenoids, essential oils, and amino acids, while saponins and anthraquinones were absent. Physicochemical parameters such as total ash (6.5\% w/w) and water-soluble extractive (16.8\% w/w) supported quality evaluation. These findings validate the ethnomedicinal uses of C. pareira in treating inflammatory, febrile, and reproductive disorders and provide essential pharmacognostic markers for authentication and prevention of adulteration. The study further underscores the plant{\textquoteright}s phytochemical richness, warranting advanced analytical and pharmacological investigations to substantiate its therapeutic potential.

Background: Trachyspermum ammi (Ajwain) is a medicinally significant plant belonging to the Apiaceae family, widely cultivated in various regions, including India, Iran, and Egypt. Objectives: This study provides a detailed Pharmacognostic evaluation of ajwain through macroscopic, microscopic, powder microscopy, histochemical, and preliminary phytochemical analyses, along with standardization parameters for crude drug validation. Materials and methods: Ajwain fruits were collected and authenticated by a certified botanist. Macroscopic and microscopic analyses were conducted using digital and compound microscopes. Powder microscopy, histochemical staining, preliminary phytochemical screening, and physicochemical standardization, such as ash values, extractive values, and moisture content, were performed. Result: Macroscopic observations confirmed the fruit{\textquoteright}s distinctive morphological features, while microscopic studies detailed the anatomical structure, including the presence of vittae, epicarp with papillae, and oil globules. Powder microscopy further verified characteristic elements such as anomocytic stomata, fibers, annular vessels, and phenolic compounds. Histochemical tests revealed the presence of bioactive compounds like alkaloids, flavonoids, lignin, and mucilage, which contribute to its therapeutic properties. These findings substantiate the traditional medicinal applications of ajwain, particularly in gastrointestinal and respiratory treatments. Conclusion: The study provides essential diagnostic markers for quality control and standardization in herbal medicine, laying a foundation for future pharmacological investigations.
