Reaction Steps

mangiferin 4.2 g (0.01 mol) is dissolved into 50 ml DMSO, calcium hydroxide 0.37 g (0.005 mol) is dissolved in 80 g glycerol, calcium hydroxide solution is added slowly into mangiferin solution while mixing round, mixing round until it react completely. Appropriate quantity ethanol is added into the reaction solution, mixing round adequately. A lot of deposition is come into being in solution. The reaction solution is filtrated to get the deposition. This deposition is heated up no excess 60° C. to dry. The yellow green solid substance is mangiferin calcium. Its weight is 3.8 g, the productivity is 90.4%. The purity of mangiferin monopotassium is 71.2% detected by HPLC.
