To investigate effect of demethoxycurcumin on stability of curcumin.To add the demethoxycurcumin to pure curcumin, the change of curcumin was determined by HPLC and the dynamics of curcumin degradation was investigated.The stability both obtained from alcohol and demethoxycurcumin improved the stabilization of curcumin, the demi-period of curcumin prolonged with the addition of demethoxycurcumin.The commixture of curcumin and demethoxycurcumin are more stable than pure curcumin at the same conditions. Stability of curcumin is improved by demethoxycurcumin,it is crude stabilizing agent.
