Cassia obtusifolia is an important medicinal plant medicinal plant. The present work deals with phytochemical screening, UV and FT-IR spectroscopy of ethanolic extract of Cassia obtusifolia seed. In phytochemical screening the extract shows the presence of carbohydrates, glycosides, phytosterols, terpenoids, phenolic compounds, tannins, proteins, amino acids, flavonoids, gum and mucilage. The UV and FT- IR spectroscopy of ethanolic extract of Cassia obtusifolia seed shows the presence of aromatic nature of compound, 3° amine, amide, alkene (Naphthalene), Amino , Ketones, aldehydes, alkyl halides, aliphatic amines, alkanes, alkenes. The above mention bioactive compound are mainly contributed in medicinal utility of the plant.
Keywords: Cassia obtusifolia, phytochemical, UV spectroscopy, flavonoids, chromophoric groups.
