With the help of cinnamoylation of mangiferin in the solution of cinnamoyl chloride (C 9 H 7 ClO), mangiferin was reacted in the presence of pyridine at room temperature for 20 hours with continuous stirring. The resulting reaction mixture was kept for evaporation, which gave a residue that was fractionized with the solvent-solvent separation technique using the ratio of solvents, chloroform:methanol (9:1). The residue was washed with water and extracted with ethyl acetate. The combined organic layer was collected and concentrated to get the desired compound 2.
