Objective:To study on the stability of stilbene glucoside in various extracts of medicinal materials from compound Xuezhining
and to explore compatibility rule of this compound. Method:The content of stilbene glucoside changed with time under different conditions was investigated by UPLC.Based on the chemical reaction kinetics
the parameters of degradation kinetics were calculated under different environments.The activation energy and half-time(t1/2) were investigated. Result:The degradations of stilbene glucoside in different conditions were followed the first-order reaction kinetics.The degradation rate constant (K) of stilbene glucoside in aqueous solution and Crataegi Fructus extract were 0.037 5
0.012 3 h-1
and t1/2 were 18.48
56.35 h under pH 8.3
respectively.The other extracts also showed the stabilizing effect on stilbene glucoside under different conditions. Conclusion:The compatibility of Chinese medicines in compound Xuezhining can improve the stability of stilbene glucoside in different degrees.Among them
effect of Crataegi Fructus is the most significant.
