PRELIMINARY STUDIES OF PHYTOCHEMICAL INVESTIGATION ON COASTAL MEDICINAL PLANTS OF BOLOOR, MANGALORE

The present study was aimed to screen the phytochemicals present in five different solvent extracts of Ipomoea –per caprea, Premna serratifolia and Synadenium grantii.Qualitative estimation of three coastal medicinal plants were performed to identify the constituents such as alkaloids, flavanoids, saponins, phenols, glycosides, tannins, steroids, terpenoids, phlobotannins, coumarins, carbohydrates, proteins and vitamin C by standard method.All the selected coastal medicinal plants were containing the primary phytochemicals of carbohydrates, proteins, and vitamin C. Moreover, coumarin was also present in all the selected plants extracts except ethylacetate leaves extract of Premna serratifolia. Least number of phytochemicals were present in chloroform stem extracts of Ipomoea –per caprea (7/13) and ethyl acetate leaves extract of Premna serratifolia (7/11) were shown to exhibit very weak results. Aqueous extracts of leaves and stems of Premna serratifolia (12/13) showed most number of metabolites. These studies provide the evidence that leaves of Premna serratifolia is of maximum remedial efficacy possessing mainstream of phytochemical classes of compounds and stem of Ipomoea –per caprea is has found to exhibit lowest therapeutic potential due to the lack of majority of phyto constituents.
