Pharmacognostical evaluation of Hibiscus radiatus leaf has been carried out to determine its macro and microscopic characters, and also some of its quantitative characters as per WHO guidelines. The Pharmacognostical evaluation of Hibiscus radiatus leaves revealed the presence of characteristic microscopic features of the crude drug like small epidermal cells, parenchyma greatly in shape, xylem vessels is numerous, Phloem is small in size etc.The Physicochemical analysis showed significant values for moisture content, water soluble extractive, alcohol soluble extractive and total ash which are within the World Health Organization (WHO) standards for crude drug from medicinal plants. All the parameters evaluated in the study will aid to identify the authenticity of Hibiscus radiatus Cav. leaf even from the crushed or powdered form.
