The objective of this study was to identify different phytochemicals present in aqueous leaf extracts of Azadirachta indica and Ricinus communis, aqueous flower extract of Calotropis gigantea. Aqueous extracts of these plants were prepared and subjected to qualitative phytochemical and UV spectrum analysis. The presence of various phytochemical compounds was determined using standard screening tests and the results indicated the presence of alkaloids, flavanoids, saponins, Terpenoides in all three plant extracts. Uv spectrum analysis of A. indica, C. gigantea and R. communis showed absorption maxima at 286, 271 and 281 nm, respectively.

It may be concluded that out of 2 plants under study, Syzygium aromaticum had higher potential anthelmintic activity (6 times more potential than Melia dubia) against contortus worms of sheep. Extensive studies need to be carried out to identify the pharmacologically active compounds in S. aromaticum that are playing key role in killing the worms and reducing the hatchability of eggs. Further validation with in vivo trials is of utmost significance.
