Studies on Pharmacognositic Parameters and Phytochemical Screening of Oroxylum Indicum Leaf

Abstract

Background: To confirm reproducible quality of plant material, proper regulation of starting material is important. Thus, there has been an increase in the standardization of selected herbal plants of potential medicinal values. Identification of herbal drugs by pharmacognostic studies is more reliable. Till date there is no work on pharmacognositic evaluation and phytochemical screening of Oroxylum indicum leaf. Therefore, the current study designed to the pharmacognostic parameters of the leaves of Oroxylum indicum. Materials and Methods: Several quality control parameters like morphological study, transverse section, powder microscopic evaluation, leaf constants parameter such as stomatal index, physicochemical evaluations (moisture content, ash values, extractive values), preliminary phytochemical screening were carried out. Results: Major microscopic characters such as Spongy mesophyll, Upper palisade, stomata and trichomes. Phytochemical screening of several extracts of leaves indicated the presence of phenolic compounds and flavonoids in the methanol extract and in aqueous extract exhibited the presence of alkaloids and phenolic compounds. Conclusion: The quality control parameters bring referential information for proper identification of the herbal material and will also be useful in preparation of monographs.
