    Objective: This study was undertaken to carry out pharmacognostical studies and phytochemical studies on aerial parts of Trichodesma indicum R. Br belonging to the family Boraginaceae.Methods: The aerial parts of plant leaf and stem were evaluated for pharmacognostical studies such as macroscopy, microscopy, powder study, and quantitative microscopy. The powder was evaluated for proximate analysis like ash vale, extracting value, moisture content, swelling index, elemental analysis, fluorescence analysis, and preliminary phytochemical studies.Results: Transverse section of leaf of T. indicum R. Br. showed presence of covering trichomes with bulbous base upper and lower epidermis, collenchyma, prisms of calcium oxalate, vascular bundle and palisade cells. Surface preparation showed the presence of wavy epidermal cells, anomocytic stomata, anisocytic stomata, trichomes. Transverse section of Stem of Trichodesma indicum R. Br showed the presence of trichomes with, epidermis, hypodermis, cortex, xylem and pith. Powder study of aerial parts of T. indicum R. Br showed the presence of trichomes, xylem vessels, parenchyma, epidermal cells, fibres, calcium oxalate crystals. The powder of aerial parts was evaluated for proximate analysis such as ash value, extractive value, moisture content, total solid content, and the swelling index, which give idea about the presence of siliceous material, and amount of constituents extracted into different solvent. The elemental analysis of aerial parts showed that plant was free from heavy metal contamination i.e. arsenic, lead. The fluorescence analysis of plant powder showed that plant contains phenolic compounds. Qualitative chemical examination showed that the aerial parts of Trichodesma indicum R. Br, is credited with phytosterol, triterpenoids, tannins, phenolic compounds, carbohydrates, fixed oil, fatty acids mucilage.Conclusion: The study reveals specific identifying characteristics for the particular crude drug which will be of significant use in identification and control to adulteration of the raw drug and can serve as a reference for any further investigations.Â

    This review article encompasses the various evaluation parameters of standardization of different medicinal plants and its constituents. In today’s life, more and more people of the world are turning towards the use of natural or herbal products as these have very less or negligible side effects. As the use of herbal medicinal products is increasing day by day, the questions regarding their quality are also arising. This is due to lack of parameters for the standardization of these products. There is a need to set different parameters or methods that can help to standardize the herbal medicinal plant materials. Various methods like physical, chemical, biological is used for standardization and quality evaluation of herbal medicinal plants. These methods can act as a basic tool for the quality evaluation of herbal plant materials. Different parameters of standardization are the fundamental tool for evaluating and assuring the quality of the herbal plant material and its products. This review article includes the quantitative evaluation of more than 20 herbal drugs. The evaluation parameters such as TLC, HPLC, HPTLC, GC, LC-MS, UPLC, UHPLC, UPLC-MS, UHPLC-MS will help to maintain quality of different herbal medicinal drugs as well as its formulations. The set parameters can ultimately lead to the quality and efficacy of the herbal medicinal formulations. Analytical methods and standardization can ensure the quality and consistency of active ingredients in herbal medicinal formulations
