Pharmacognostical and phytochemical investigations of a terrestrial and an aquatic plant

Abstract

This paper describes the Pharmacognostical and Phytochemical screening of selected plants that is Procris repens and Sargassum duplicatum. Procris repens (Lour.) B.J.Conn & Hadiah belonging to the family Urticaceae commonly called as ‘Trailing Watermelon Begonia’ and ‘Wavy Watermelon Begonia’. Sargassum duplicatum J. Ag. is one of the main seaweeds in the marine ecosystem that has been used as a source of medicine among brown seaweeds belonging to the family Sargassaceae. This review paper discusses in detail study of Pharmacognostical and Phytochemical screening. In Pharmacognostical study discusses the microscopy and macroscopy of selected plants. Here the macroscopical study describe the characters like colour, odour, taste, size, shape, extra features of the leaves. The microscopical study describe the fresh leaves were subjected to various anatomical studies. The sections of leaf specimen were taken using sharp blade and stained with various staining reagents like phloroglucinol-HCL, iodine, safranin and observed under microscope. Phytochemical screening of Procris repens found to contain alkaloids, steroids, triterpenoids, saponins, glycosides, tannins, phenolic compounds and flavonoids while in addition to it Sargassum duplicatum extract also contain carbohydrate also.
