The main objective of this study was to evaluate the phytochemical and antioxidant properties of leaves of Carica papaya and Mangifera indica and seeds of bitter gourd cultivated in the Bangalore region of Karnataka. The leaves of Karnataka papaya and M. indica and seeds of M. charantia were extracted with different solvents such as water, methanol, and ethyl acetate. The preliminary phytochemical screening was performed by standard methods as described by Harborne. The tests indicate the presence of alkaloids, tannins, flavonoids, and the absence of saponin and glycosides. The total phenolic content (TPC) was determined by the Folin-Ciocalteu method. In addition, leaf and seed extracts of methanol were analyzed by high-performance liquid chromatography to identify bioactive compounds. The results confirmed that extracts of M. indica and C. papaya and M. charantia accumulate large numbers of phytochemicals, but the higher percentage is related to phenolic compounds. These findings are helpful to the phytochemist and pharmacologists for the identification of new active principles in the future.
