Comparative studies of secondary metabolites using qualitative tests was performed on Cassia spectabilis, Cassia siamea, Cassia fistula, Cassia biflora and Cassia hirsuta. Qualitative analysis was done for various phytoconstituents like alkaloids, tannins, saponins, anthraquinones, anthocyanosides, phenolic flavonoids, flavonoids, carbohydrates, proteins, steroids, terpenoids, cardiac glycosides and phlobatannins.The leaf extracts were prepared using various solvents like ethanol, methanol and ethyl acetate to detect the presence of the active components. The phtyo chemical screening revealed the presence of all the above chemical constituents except anthraquinones, anthocyanosides and phenolic flavonoids.
