This study deals with the identification of secondary metabolites of methanol extract of the roots of Mangifera indica L and the assessment of plant in vitro anti-inflammatory activity. High-performance liquid chromatography with electrospray ionization mass spectrometric detection (HPLC-ESI-MSn) using the negative ion mode was performed to establish the chromatographic fingerprint and identify various chemical components of the plant extract. The anti-inflammatory effect of the MeOH extract (3, 30 and 300 μg/mL) was assessed through cell viability and nitric oxide (NO) production on non-stimulated and LPS-stimulated peritoneal macrophages. Phytochemical analysis indicated the presence of a number of phenolic compounds where galloyl derivatives, mangiferin and its derivatives were the major constituents. The methanol extract exhibited significant concentration-dependent inhibitory effect on NO production, both on stimulated and non-stimulated macrophages. The concentration 300 μg/mL showed significant cell toxicity. The methanol extract of Mangifera indica is rich in phenolic compounds and possesses potent in vitro anti-inflammatory activity, but its higher concentrations are cytotoxic.
