Phytochemical evaluation and anticancer activity of rambutan ( fruit endocarp extracts against human hepatocellular carcinoma (HepG-2) cells.

The current investigation was taken to screen the phytoconstituents present in fruit endocarp various extracts of commonly called as Rambutan fruit and its anticancer property against human hepatocellular carcinoma (HepG-2) cells. Different analytical techniques including qualitative phytochemical analysis, cell viability assay (MTT), apoptotic nuclear staining (DAPI), DNA fragmentation assay, Attenuated total reflection (ATR) and Gas chromatography-mass spectrometry (GC-MS) spectral analysis were carried out. ATR and GC-MS study revealed the presence of functional groups and 9 compounds, respectively in methanol endocarp extract. The results obtained depicts that methanol endocarp extract profoundly controlled cell proliferation and caused shrinkage of HepG-2 cells from polygonal to spherical shape. DAPI staining revealed that methanol endocarp extract caused increased fragmentation of nucleus and DNA fragmentation, which can be taken as a sign of apoptosis. The anticancer potential of methanol fruit endocarp extract of than other extracts and could be used successfully in future drug delivery systems and other biomedical concerns.
