Abstract

This pharmacognostic study deals with the leaf-anatomy of Nyctanthes arbor-tristis L., an Indian plant, used in indigenous medicine throughout India from time immemorial. Features like anomocytic stomata, cuticular striations on subsidiary cells, occasional oval or flask shaped epidermal cells, peltate quadripartite glandular trichomes, non-glandular trichomes with smooth or rough surface (spiculate or waxy flaked) and some round bluish bodies appear to be characteristic for the leaves of this species. Fluorescence characteristics of the leaf dust under different chemical treatments using UV and ordinary light have also been recorded for pharmacognostic standardisation.
