A Metabonomic Study of the Effect of Methanol Extract of Ginger on Raji Cells Using (1)HNMR Spectroscopy.

Cancer is currently a major international health problem. The development of resistance to chemotherapy has resulted in the search for herbal drugs. Ginger is a medicinal plant with several clinical applications. Metabolomics is a simultaneous detection of all the metabolites by use of (1)HNMR or mass spectroscopy and interpretation by modeling software. The purpose of this study was to detect the altered metabolites of Raji cells in the presence of ginger extract in vitro. Cells were cultured in the presence and absence of methanolic ginger extract in RPMI medium. IC50 determined by MTT and lipophilic and hydrophilic extracts were prepared from control and treated groups which were analyzed by (1)HNMR. The IC50 was 1000 μg/mL. Modeling of spectra was carried out on the two groups using OSC-PLS with MATLAB software and the main metabolites detected. Further analysis was carried out using MetaboAnalyst database. The main metabolic pathways affected by the ginger extract were detected. Ginger extract was seen to effect the protein biosynthesis, amino acid, and carbohydrate metabolism and had a strong cytotoxic effect on Raji cells in vitro.
