PRELIMINARY SCREENING OF PHYTOCHEMICALS IN PAPAYA LEAF, BARK AND PEEL OF PAPAYA FRUIT

Plants provide pharmacological important substances. Preliminary phytochemical screening is a vital step to detect and isolate bioactive constituents who may lead to provide ecofriendly environment and help in novel drug discovery. The study was design to investigate the phytochemical screening of various solvents extract of different parts of Carica papaya . Phytochemicals,  also known as bioactive constituents  are  secondary metabolites of plants which have  medicinal uses. Alkaloids, flavonoids, steroids, saponin, tannin, glycosides are bioactive constituents present in Carica papaya commonly known as papaya plant. Papaya has not only neutraceutical value, it has potential medicinal properties also . The crude extract obtained from the leaves ,bark and peel of Carica papaya in various solvents like petroleum ether, benzene, chloroform, acetone, ethanol, aqueous and extracts were subjected to phytochemical screening .The test conducted in triplicate and the qualitative determination of different metabolites was done using analytical standards published in a text book. The phytochemical screening revealed the presence of saponin in the extract of leaf and bark on the other hand it is  absent in the  peel of papaya. This research paper will be helpful for pharmaceutical industry in discovery of novel drug.
