ABSTRACT
Plants and their secondary metabolites have stimulated the development of innovative
medications as well as a return to the use of herbal therapies for a variety of diseases. In the
present study, an attempt has been made to identify the active ingredients present in
Phyllanthus emblica pulp and Vitis vinifera pulp. The pulp of these plants was extracted by
different solvents and subjected to phytochemical screening to assess the best extraction
medium. Both the extracts were analyzed qualitatively and quantitatively for the presence of
phenolics and flavonoids. The antioxidants in the fresh pulp of these plants were analyzed to
determine the total antioxidant capacity of these plants. Finally, spectral studies were carried
out to find the presence and structure of flavonoids in the Phyllanthus emblica and Vitis vinifera
pulp juices. The antioxidant analysis of Phyllanthus emblica and Vitis vinifera pulp show near
equal levels of antioxidant activity when compared with standard ascorbic acid. Quercetin, one
of the flavonoids present in the extracts was identified by HPLC and the same has been
confirmed by spectral studies. To summarize, the selected fruit pulps showed very notable
biochemical flavonoids that are both beneficial and economical.
