The present study reveals the pharmacognostic studies root of Stachytarpheta jamaicensis (L) Vahl. The objectives of the present work comprises of collection, identification, macroscopical, Ph of aqueous solution, soluble ash, alcohol soluble extractive, flouresence analysis of root. The root section was taken and microscopical studies were carried out, the root shows derived from the cork, the periderm tissue is formed, which replaces the epidermis in the outer layer. The next tissue identified inwards was the cortex. Sclerenchyma was seen as a ring in the roots, while as a group, formed from a group of cells, in the mature ones. In the middle, xylem tissue occupies a large area, just below the phloem tissue.

Pharmacognosy of the flowers of Saraca asoca (Roxb.) De Wilde has been carried out to lay down standards for the genuine drug Ashoka with the detailed anatomy of various floral appendages. The aim of the present study is to determine the physico-chemical profile, preliminary phytochemical screening, fluorescence analysis and chemical composition by HPTLC of the medicinally important plant Saraca asoca. These observations would be of immense value in the botanical identification and standardization of the drug in crude form. This study would help distinguish the drug from its other species.

In the present study of Jasminum sambac ethnobotanical and pharmacognostical activity of Jasminum sambac leaf .These species of highly medicinal purpose flowers, leaves act as lactifuge, arrest the secretion of milk in the puerperal state in case of threatened abscess pharmacognostical study of leaf parts of Jasminum sambac has been undertaken, hence it is establish. Pharmacognostical and quality control parameters of leaf, of Jasminum sambac was carried out. Various microscopic characters viz., transverse section of leaf, quantitative parameters (stomatal number, stomatal index, and vein-islet and termination number) were determined for the identification of plant material. Powder microscopic studies, were also performed. Physicochemical parameters such as total Ash(13.5%), water soluble ash (6.7%) and acidinsoluble ash (8.2 %)Alcohol soluble extractive(30%) Water soluble extractive(11.8%)Moisture content(6.19%)Crude fibre content(15.1%)Swelling index (1)and Foaming index (Lessthan 100).
