Abstract:
Stability constant of ascorbic acid a nd lea d complex was measured by pH potentiometry at different tempcraturcs and concentrations of monoammonium glycyrrhizinate (MG ).At a concentration of 5.0?10-4mol/L and at biolugical condition, lgk1 = 8.72 and lgk2 =6.91. The result suggestod that the stability constant can be imptoved at decreased temperatures and increased concentrations of MG.
