Cytotoxicity Screen of Mangiferin and its Major Metabolite Norathyriol in Human Tumor Cell Lines

Many natural products are available worldwide as potential chemoprotective agents against commonly occurring cancers, for example Mangiferin which has low bioavaiulability and is thought to be mainly available in the colon.

Many studies have shown that human fecal bacteria (HFB) can have a great impact on polyphenol metabolism and that bioconverted forms of polyphenols (metabolites) probably have more biological importance than the native form present in diets.
