Caesalpinia bonduc (Cucurbitaceae) commonly known as Ivy Gourd is an important plant used against various disorders in indigenous system of medicine such as antioxidant, antidiabetic, laxative , used in the treatment of rheumatoid arthritis and immune system modulator. Thus from the extensive literature survey it was revealed that no reports were available on microscopic evaluation, standardization parameters and chemo profile of Caesalpinia bonduc and to check the identity and purity of the drug. The present work embodies the investigations carried out to establish methods for quality control of drugs as per who guidelines which includes macroscopical features, physicochemical parameters like loss on drying, foreign matter, extractive value, ash value and to investigate the phytochemical present in the extract in the preliminary level with respect to thin layer chromatography were also carried out for the quality control of the drug. Thus, it was thought worthwhile to explore this plant on the basis of these standardization parameters. The study will provide referential information for the correct identification of the crude drug. Keywords: Caesalpinia bonduc, standardization, phytochemical studies, extraction
