ABSTRACT
AIM:
To study the decomposition reaction kinetics of aqueous salvianolic acid B(Sal B).METHODS:
HPLC was applied to determine Sal B's content of samples.Relationship between Sal B's content and heating time was regressed.RESULTS:
Decomposition reaction of Sal B's aqueous solution was first order reaction.The effect of temperature on reaction rate of Sal B's decomposition was higher than pH value.At lower temperature(50℃),reaction rate constant K of Sal B's decomposition was very low and it changed very little with pH values.CONCLUSION:
Water extraction process of Salvia Militiorrhiza should avoid applying high temperature,alkaline condition and long heating time in order to reduce loss and decomposition of Sal B,and then also increase Sal(B's) content in the extract.
