The aim of the present study is to evaluate the Pharmacognostical and Phytochemical studies of Aerial parts of Tabernaemontana divaricata. The plant belongs to the family Apocynaceae, a common garden plant in tropical countries has been used as antioxidant, anti-infection, anti-tumour and analgesia as a folk medicine in India, Sri Lanka, Malaysia and Thailand. Hence in the present work the Aerial parts of the plants were subjected to physical, microscopical, physiochemical and phytochemical evaluations. Microscopical transverse section of leaf showed a narrow upper epidermis with palisade, vascular bundle at the centre with a narrow zone of spongy parenchyma and a continuous mass of thin walled ground tissue towards the phariphery. T.S. of stem showed a thin elongated single layer of upper epidermis with hypodermis, followed by continuous mass of thin walled parenchymatous cells of cortex and vascular bundles containing xylem and phloem cells towards the periphery. The powdered aerial parts showed the presence of anisocytic stomata, unicellular trichomes, bundle of phloem fibres and calcium oxalate crystals. Physicochemical parameters such as ash values and extractive values and preliminary Phytochemical screening of methanolic extract of Tabernaemontana divaricata were also carried out. These findings might be useful to supplement information in regard to its identification parameters, which could help in the development of a suitable monograph for the plant.
