The pharmacognostic investigation was carried out in terms of macroscopic, microscopic parameters. The extract obtained after successive Soxhlet extraction of dried and coarsely powdered stem bark using Petroleum ether, chloroform, ethanol and distilled water were subjected to a preliminary phytochemical screening which revealed the presence of Carbohydrates, Proteins, phytosterols and triterpenenoids. The present investigation reflects the structural identity and chemical nature of the crude drug which could be useful in laying down pharmacopoeial standards as standardization is an important aspect in assessing the quality, safety and efficacy of herbal medicines.Key words:Ailanthus excelsa roxb , pharmacognostic, phytochemical, structural identityKeywords:Ailanthus excelsa roxb, Pharmacognostic, Phytochemical, structural identity.
