Herbal drugs constitute a major part in all the traditional systems of medicine. One of the traditionally acknowledged plant Erythrina variegata, commonly known as Indian coral tree belonging to the family Fabaceae has been widely used forayurvedic therapies. Due to the scarcity of standardization reports of this valuable medicinal plant the pharamacognostic, morphological, microscopical and chemical characterization studies of the leaves of Erythrina variegata Linn,syn were performed. Anatomical investigations of theepidermal study of leaves revealed sessile glandular trichomes on both the epidermis of the leaves. Paracytic and anisocytic stomata only on the lower epidermis of the leaf were observed.The Fluorescence analysis of leaves powder of E. variegata Linn,syn revealed a range of colours from dark green, yellow to brownish black under short Ultra Violet (UV) light. Various quantitative parameters like ash values, extractive values and moisture content that can be used as quality control parameters for E. variegata Linn,syn were determined. The air dried leaf powder methanolic extract fingerprinting pattern was developed by using High Performance Thin Layer Chromatography (HPTLC) technique which showed eight well resolved components.The pharamacognostic studies carried out for E. variegata Linn,syn and presented here provide referential information for the identification of this crude drug and will also help in distinguishing it from its adulterants.
