C Yogeshwari and K Kalaichelvi
The study was aimed at analysis of potential bioactive constituents of aerial parts of Acmella calva (DC.) R. K. Jansen and Crotalaria ovalifolia Wall. The qualitative phytochemical screening was done using ethanol and water as solvents. Alkaloids, flavonoids, tannins, phenols, glycosides, proteins and amino acids, carbohydrates, terpenoids, saponins, quinones, anthroquinones, gum and mucilage were qualitatively analysed. The aqueous extract gave better result which indicated the presence of alkaloids, phenols, tannins, flavonoids, saponins, terpenoids, carbohydrates, coumarins and quinones. Terpenoids were absent in Crotalaria ovalifolia. Anthraquinones, protein and aminoacids, fixed oil and glycosides were not deducted in both the extracts of study plants.
