Studies on Degradation Kinetics of Puerarin in Aqueous Solution
摘要
Abstract
Objective:To investigate the degradation kinetic characteristics of puerarin in aqueous solution under different pH and temperatures.Methods:The concentration change of puerarin in aqueous solution was determined by HPLC under different pH and temperatures.Based on the chemical reaction kinetic,the parameters of degradation kinetics were calculated.The activation energy and half-life were evaluated.Results:The results indicated that thermal degradation kinetic model of puerarin in aqueous solution follows first-order degradation kinetic process.Conclusion:Puerarin was more stable in neutral aqueous solution and low temperature condition.The degradation of puerarin can be observed in both strong acid and strong alkali conditions.关键词
