“…A detailed pharmacognostic assessment therefore is extremely an important prerequisite. In accordance with WHO, the macroscopic and microscopic description of a medicinal plant is the primitive step in the direction of establishing its identity and purity and need to be performed prior to any tests tend to be carried out [21][22][23] .…”

“…racemosa, traditionally utilized in conventional medicines has incredible therapeutically potential due to its multifaceted biological functions. Microscopy is one of the straight forward and modest strategies to begin with setting up the correct identity of the source [21][22][23] . Here, preliminary phytochemical examination of the stem revealed the presence of saponins, flavonoids, tannins, phenols, glycosides and volatile oils.…”

In accordance with World Health Organization (WHO); traditional medicines are utilized by 70-95% of worldwide population especially in developing countries with regard to their healthcare. Additionally, the usage of herbal drugs has grown incredibly in line with the worldwide trend of folks returning to natural remedies. The increasing utilization of botanicals by the public is forcing moves to evaluate the health claims of these agents and also to establish specifications of quality and manufacture [1] .Herbal drugs exert a key impact in health care programs particularly in developing nations. However hindrance behind the acceptance of herbal medicine in developed nations is the lack of documentation, stringent quality control measures. Therefore, documentation and standardization of the crude materials utilized in herbal medicine is vital for the global compliance of this system of medicine. In this regard, WHO supports the nations to provide conventional remedies and practices in communal and private health services. Construction of monographs are planned fundamentally to promote harmonization in the utilization of herbal drugs with respect to levels of safety, efficacy, and quality control. Pharmacognostic standardization, physicochemical investigation and preliminary phytochemical studies were all over accepted in recognizable proof and confirmation of the genuine plant materials. Standardization of herbal drugs is the strategy of recommending a set of specifications, constant parameters, definitive qualitative and quantitative values, which bring an assurance of quality, efficiency, safety as well as reproducibility. Proper identification and quality assurance of plant materials are essential to ensure reproducible result of herbal medicines, which will add to its safety and efficacy.

The data presented in this article are related to the scanning electron microscope and elemental studies in the four species of Bignoniaceae namely Tecoma gaudichaudi DC (Sample 1), Tecoma capensis (Thunb.) Lindl. (Sample 2), Tecoma stans (L.) Juss.Ex Kunth (Sample 3), Tabebuia rosea (Bertol.) (Sample 4). The SEM images were obtained for permanent record. The abaxial and adaxial surfaces of each species were carefully studied. In addition to this, the consistent occurrence of anomocytic stomata in all four species of this family shows that morphological and taxonomically all the species are very close and intimate.The elemental data on leaf samples of all four species were performed and total eight important components were present such as C, O, Mg, Al, Si, Cl, K, Ca. These elements are useful, so identification of inorganic components of these species defiantly helps to promote as dietary elements.

The current study was considered with the aim to set up the standardization parameters for Senecio laetus for its identification and to determine its purity and quality. Innumerable parameters for the standardization of plants like macroscopy, microscopy and physicochemical parameters, fluorescence studies and preliminary phytochemical analysis were accomplished. Macroscopical and microscopical studies were carried according to the day-to-day laboratory norms. The guidelines of World Health Organization were considered for phytochemical screening and florescence analysis of the plant. Microscopy of leaf and stem helped to reveal the anatomical structures, which are to be reported for the first time for this plant species. Analysis of the powders of leaf, stem and flower revealed the presence of epidermal cells with stomata, trichomes, lignified vessels, calcium oxalate crystals, starch granules, xylem vessels, parenchyma cells, cork cells and pollen grains. Phytochemical analysis ascertained the presence of carbohydrates, phenols, glycosides, saponins, flavonoids, tannins, etc. Physicochemical parameters like ash values, extractive values, loss on drying, foreign matter analysis, foaming index, determination of pH and fluorescence were studied. All these parameters are valuable in differentiating the powdered drug. The conclusions from these experiments will help in providing the values of various parameters for the standardization and identification of S. laetus.
