Food bioactives offer a great potential in the fight against human cancer by inhibiting the carcinogenesis process through cell defensive and apoptotic machineries. Fruit Peel is a major by-product of processing food and are not currently used commercially, but it can be a potential chemo-preventive agent. In this study, we have evaluated peel of citrus and pitaya against various cancer cell lines and figure out the possible mechanism of action in specific cancer cell line via apoptosis approach. The results suggest that inhibition of cell proliferation or the induction of cell death in various cancer cells by fruit peel metabolites might be mediated by the induction of sub-G1 phase arrest and the subsequent apoptotic process that is accompanied by caspase-3 activation, as it caused the degradation of several important substrates, including PARP. Further, a compositional/metabolomics analysis of the fruit peel was performed using HPLC-ESIMS/ MS to identify which phytochemicals are responsible for the anticancer activity. The phytochemical-induced apoptosis may result from the combined or synergistic actions of a mixture of metabolites found in the fruit peel. Thus the purpose of this presentation is to discuss the process of apoptosis and the potential effect of metabolites of fruit peel against cancer prevention.
