These three plants are reported to possess antidiabetic activity. Study Design: The plants were collected, authenticated and Macro-morphological, qualitative and quantitative microscopic features as well as physicochemical, fluorescence analysis, phytochemical properties, and thin layer chromatography (TLC) Place and Duration of Study: The study was carried out at College of Pharmacy, Dr. APJ Abdul Kalam University, Indore, during 2019-20 Methodology: The material were collected, authenticated and Macro-morphological, qualitative and quantitative microscopic features as well as physicochemical, fluorescence analysis, phytochemical properties, and thin layer chromatography (TLC) profile of Phyllanthus amarus, Glycerrhiza glabra and Piper nigrum were determined using standard methods.
