Abstract : Leaves and fruits of Mangifera indica Linn. are widely used in traditional Ayurvedic preparations like Pushyanuga Churna, Amrapanaka, Khandabhrakam, Vridhagangadhara etc. Till date there are no pharmacognostical scientific work done on its leaf. The present study was planned to do the micro-morphological and micrometeric study on the leaf of Mangifera indica Linn. Histo-chemical tests were done by using thick sections to observe the presence of tannins, lignin, starch etc. Both upper and lower epidermis was used for the surface study through hand peeling method. Micrometric readings of both surface i.e. Stomatal length, stomatal index etc. were scientifically studied and the mean value was taken in to consideration. Leaf powder was used for micro-morphological analysis. Histo-chemical test were done by using thick sections to observe the presence of tannins, lignin, starch etc. Results showed stone cells and starch grains in petiole, 2-3 layer of pallisade parenchyma, pitted vessels in leaf, stomatal index i.e. 26 in lower epidermis. Powder microscopy of shade dried powder showed prismatic crystals and oil globules. The information generated in this study will be helpful for the proper identification and authentication of leaf of this herb.
